Read full descriptionHide full description
Two ways to play in one cozy slime world: think your way through 100 handcrafted Slime Stack puzzles, or drop, match, and evolve slimes in quick physics runs. SLIME STACK — 100 MERGE PUZZLES • Move the top slime between three pegs. Matching tiers evolve into bigger slimes. • Smaller slimes can rest on larger ones, so every placement counts. • Set up chain reactions: a whole cascade of evolutions costs just one move. • Reach the target tier within the move limit, and solve in the fewest moves for three stars. • Undo your last move or reset as often as you like. • Ten chapters, from First Moves to Stack Mastery, with Bits to earn along the way. DROP MODES — QUICK PHYSICS RUNS • Arcade — race the drop clock and build the biggest chain you can. • Daily — play the same seeded challenge and chase the global leaderboard. • Cozy — slow things down with an untimed, relaxed run. Earn Bits as you merge, unlock collectible visual theme packs, and rescue crowded boards with Starburst and Prism Shift powerups. Every theme has ten handcrafted evolution tiers, from tiny starters to screen-filling champions. Slimefall Arcade combines tactile drop controls, lively physics, cheerful sound, and quick portrait play for a merge game that is easy to start and rewarding to master.

Train your brain with logic. Fall in love with the birds. BirdBrainz is a colorful puzzle where a flock of feathered friends absolutely refuse to share a row, a column, or so much as a diagonal glance. Your job: figure out exactly where each one belongs, using nothing but deduction. Every puzzle is generated to have exactly one solution. There's no guessing required—only logic. Place a bird where the others don't like, and the newcomer startles them away, feathers ruffling in a huff. Whether you have two minutes or twenty, BirdBrainz offers relaxing puzzles that reward careful thinking—and a cast of characters that make solving them fun. FEATURES • More than 40,000 puzzles • One unique solution for every puzzle • Beautiful animated bird artwork, with signature reactions for every species • Six difficulty tiers, from a gentle warm-up to seriously tricky, unlocking as you improve • Helpful hints when you're stuck • Simple controls—tap or drag birds into place EASY TO LEARN Each bird has its own home. Birds don't share rows. Birds don't share columns. Birds can't perch next to other birds, even diagonally. Those simple rules combine to form a huge range of puzzles, from simple to seriously tricky. HOWEVER YOU LIKE TO SOLVE You can mark off every impossible cell before placing a single bird — total certainty, one step at a time. Or you can place a bird the moment it feels right, then backtrack if a bird objects. Most of the time you'll land somewhere in between, and BirdBrainz keeps up either way: mark, place, undo, repeat. There's no wrong way to think it through. MEET THE CAST You'll start with 5 recurring birds and meet 4 more as you progress—from the bold red Cardinal and the sharp-crested Blue Jay to the tiny, hovering Hummingbird and the round, watchful Snowy Owl. Each one has its own look, its own moves, and its own opinion about being told where to sit. RELAXING No timers. No rushing. No pressure. Just you, colorful birds, and satisfying deductions. Download BirdBrainz and see how many puzzles—and ruffled feathers—you can rack up.

Verdict
The clearest difference is ads: BirdBrainz at none against Slimefall Arcade's shown. Slimefall Arcade's advantage is update cadence (every 2 weeks vs monthly) and iOS requirement (16.0 vs 18.6). On price, in-app purchases and device support there is nothing between them.
