Angry Birds maker Rovio long boasted about its ambitions to become the next Disney. And now that goal has come to fruition. The Angry Birds Movie is playing on thousands of screens around the globe. Whether or not it’s any good is another matter altogether, critics reviews seem pretty mixed. It’s a feeling we know well from the more recent entries in the Angry Birds game franchise. Which currently spans 16 titles, with a 17th, a soccer game, has deviated in surprising, sometimes underwhelming ways. Still, the series has serious highlights, so we’re taking the opportunity to rank every game from worst to best. Disagree with our clear scientific findings? Let us know in the comments.

16. Angry Birds Fight

Rovio has taken the franchise in many different directions of late, as you’ll see over the following 15 slides. Still, the developer’s clumsiest misfire is indeed Angry Birds Fight. It’s essentially the franchise’s take on the Puzzle Quest formula, only sped up; matches last about 45 seconds you have to constantly link up like icons to power up your fighter.

Strategy is minimally essential; the game constantly suggests matches, making it tough to consider your own pairings. However, the biggest issue is that the resulting combat following the puzzle sequence is automatic and unclear. You’ll often get matched up against higher-level players who dominate you. Add in multiple energy meters and hugely expensive gems the appeal vanishes.

15. Angry Birds Go

Colorful, cartoonish console game franchises often make a kart racer; Rovio did quite the same on mobile with Angry Birds Go. And honestly, there’s a fair bit to like here. It’s a beautiful game, the driving mechanics are solid, and it offers a decent amount of event variety. The problem is the game is absolutely doused with obnoxious freemium elements. Kart upgrades for higher-level rides are needed to progress. But you’ll have to grind to get anywhere or pay out huge bounties for bundles of in-game currency. The idea of paying upwards of $30 in gems for a high-level kart is mind-numbing. All the ads and the sponsored power-ups wear thin quickly. It can really rub you up the wrong way.

14. Angry Birds Epic

You’ll find some pretty epic role-playing games on the Play Store, including The Banner Saga and many classics like Final Fantasy and Dragon Quest entries. Still, Angry Birds Epic doesn’t quite fit the title. True, it takes the shape of a fantasy role-playing quest. Transforming the birds into warrior mages and tossing them into turn-based battles against armor-clad cloak pigs. But that’s all there is to it: Battle after battle, with plenty of repetition. Angry Birds Epic doesn’t have any sense of exploration or much of a storyline. Besides, are these characters powerful enough to support much narrative anyway? It’s a baffling turn for the series. Attractive and competent but pretty uninteresting otherwise. And the freemium elements can be a severe detriment to continued play.

13. Angry Birds Action

Angry Birds Action is the series’ latest attempt to spin the pull and fling formula into a new kind of experience, but more is needed. As the title teases. Action is more interested in brute force beating. Than strategic puzzle solving as you launch the birds into pinball table Esque areas. Watch them bounce around and smash everything in sight. It does offer a bit of variety: You’ll sometimes collect stolen eggs or guide baby birds back to their nest. At the same time, other stages see you smashing into TNT boxes. Or knocking around oversized soccer balls for some reason. Still, it’s a lot of randomized chaos; we never felt a strong pull to keep returning to it. At least the freemium model isn’t as harsh as it initially seems.

12. Angry Birds Star Wars II

As we’ll explain later in this piece. The original Angry Birds Star Wars is one of the best entries in the entire series. Angry Birds Star Wars II, on the other hand, is not. Surprisingly, it’s not because the second game spotlights the reviled prequel films. However, the game has fewer truly iconic sights included. It isn’t a great take on the Angry Birds formula. With more than 30 available characters to unlock or purchase. The stages are designed to be defeated by any of them. There’s often little precision needed; you’ll see many more apparent solutions. It’s just not very satisfying. Add in loads of ads and in-app purchase opportunities. This prequel-based sequel can’t live up to the first game’s legacy.

11. Angry Birds Pop!

As genre tributes go, Angry Birds Pop!, formerly Angry Birds Stella Pop!, is perhaps the most daring of the bunch. Every bit of the interface game design is cribbed from Bubble Witch 2 Saga, which was already a clone of the classic Bust a Move Puzzle Bobble games. The side-by-side comparison is laughable, but at least Rovio’s game adds more visual effects with polish. And the game itself? It’s solid but doesn’t really improve upon the familiar design. You’ll shoot colorful balls onto the screen to try to match three or more of a kind. And clear them from view. Varying objectives keep things interesting enough. The freemium design proves frustrating and can slow your progress, but it’s a slick diversion up until that point.

10. Angry Birds Slingshot Stella

Starring the titular pink heroine, Angry Birds Slingshot Stella has been described by some as a spinoff. Others as a return to the core style of series play, before Angry Birds 2’s release, of course. But ultimately, in the grand scheme of things, it tends to feel like more Angry Birds. And when it was released in 2014, that caused some well-earned franchise fatigue. If you missed it back then, Stella has its moments still. The new abilities tweak the familiar approach to some extent, letting you say, ricochet Stella from building to building. And the colorful aesthetic has something of a storybook appeal to it. The freemium elements can frustrate; however, Stella hasn’t added as much post-release content as other entries.

9. Angry Birds Friends

Angry Birds Friends, as the title suggests, is the social spinoff of the series. Rather than play solely to gain all the stars. You’ll compare your scores against those of your Facebook friends and compete in weekly leaderboard competitions. So, instead of a massive vault of levels, Friends offers up a new set every week. It’s nice to have another small stack of stories each week. Making it appointment gaming of serious fans; these levels tend to be the larger, zanier ones. Still, one big problem with a freemium game like this. The ability to buy power-ups to aid your architectural assaults takes the sting out of the competitive premise.

Unlike the Star Wars tie-ins, Angry Birds Transformers doesn’t even look or play like a classic Angry Birds game. Rather than fling fowl at buildings. Your robot bird runs along a 2D path as you blast pigs’ towers in the distance. It’s a strange little collaboration that is easy to dismiss, but surprisingly, it’s fun. There’s an entertaining rhythm to tapping targets on the enemies. Not to mention transforming into a vehicle to zip past falling hazards. The cartoonish Transformers tribute is spot-on. The only big downside here is the upgrade timers that can keep you bogged down unless you spend gems. Sold in bundles up to $100, naturally, but that’s the price of freemium.

7. Angry Birds 2

After many mediocre spin-offs, it was a relief to see Angry Birds 2 hit the App Store in 2015. Who would’ve thought it would take Rovio nearly six years to release a proper sequel to the smashing original? Whatever the case, this free-to-play follow-up returns to the core formula of old. You launch birds to crush pig-housing buildings. Still, it also shakes up the familiar design. Now you can use your birds in whichever order you’d like. Plus, you’ll typically complete three or four different areas in each level, which expands the size of the game. But also is punishing if you lose on the last part. And the newly randomized level layouts take away the obsessive fun of reading a stage and learning from your mistakes. There’s a ton to play here. It all looks great, but the tweaks to freemium elements aren’t all improvements.

6. Angry Birds Rio

Remember Rio, the colorful animated film about tropical birds? No? Kids might, but adults probably have a better memory of Angry Birds Rio, the attractive tie-in game. As the third-ever Angry Birds game, it was a big deal back in 2011. While the movie license made it seem less essential. It’s a worthwhile entry, even for those who don’t care about Rio. Essentially, Angry Birds Rio uses the occasion to switch up the terrain. Tossing you into lush jungles and warehouses full of animal cages. To crash through as you knock away marmosets instead of pigs. Rio also introduced boss battles with new playable birds while bringing a fresher art style to the series. And the 2014 release of Rio 2 added much more content to the game, too.

5. Bad Piggies

Bad Piggies was the first real spinoff from the Angry Birds formula; it’s still the best by a wide margin. It’s all a role reversal, instead of controlling the birds, you take command of the supposedly stupid pigs. Building intelligent contraptions to guide them to a goal. Even more so than the source series, Bad Piggies is a puzzle experience. It requires a lot of trial and error tinkering to get it right. You’ll construct karts, helicopters, and other makeshift vehicles using crates, propellers, balloons, and various tools. The grid-like structure makes it simple to build. Yet it is challenging to produce a fair ride to tackle the more challenging stages. It makes you wish the series opted for more of these brainier entries rather than brasher, forgettable fare.

4. Angry Birds Seasons

Launched initially as Angry Birds Halloween, Rovio’s holiday spinoff gained incredible traction. Angry Birds Seasons has continued for years, with a couple dozen level sets providing hundreds upon hundreds of playable stages. And while the original focus on holiday seasons remains mostly intact. The game has also taken amusing deviations, like the NBA-themed update. At least early on, Seasons was noteworthy for being a lot more challenging than the original Angry Birds experience. With deviously tricky levels that you’d play dozens of times to solve. Well, at least we did. It might not be as iconic as the first game, but Seasons is arguably just as strong an overall experience. However, the switch to a freemium model is frustratingly locked off from much of the content behind paywalls.

3. Angry Birds Star Wars

What could have been a quick, dirty nostalgia cash-in is pretty awesome. Angry Birds Star Wars does a great job of honoring the source material, delighting fans while also serving as one of the best showcases for the game series. You’ll relive scenes from the original film trilogy as game levels. All while playing levels as birds dressed up like Luke, Han Solo, and Lia, even sporting light saber blasters. Angry Birds Star Wars smartly splits the balance of its levels between the traditional ground levels of the core games. And the gravity-twisting stages of Angry Birds Space, providing a sharp all-in-one series experience. And if you don’t care about Star Wars, what?! The game itself is still plenty enjoyable.

2. Angry Birds

Catch us on another day. We might have this in the #1 slot instead. The original Angry Birds is an absolutely iconic game; it has grown significantly over the years to feature more than 500 playable levels. Angry Birds wasn’t the first catapult game on the market. Still, it took that basic premise and turned it into something alluring and addictive for all ages. It’s arguably still the ideal starting point for the franchise. You can see the experience progress from the relatively simple early stages to the more expansive challenges. And level designs of the later sets. Angry Birds has been updated and enhanced over time, sadly augmented with in-app purchases, but the appeal remains. It’s a true classic.

1. Angry Birds Space

After a couple years of variations on the same pull and fling theme. Angry Birds charted a new course to the stars. Angry Birds Space is the result. If the original Angry Birds seemed like a glossier riff on Crush the Castle. At least Angry Birds Space feels genuinely creative and original, putting a brand new spin on the environmental puzzler. Shifting to outer Space means playing with gravitational pull. Letting you use the fields around planets to slingshot you into bird asteroids or send objects crashing down. Taking the game off the ground added many more gameplay possibilities; Rovio explored many of them with various level updates. It hasn’t been as amply extended as some entries, but Space is still our favorite.
