Combine them into bigger animals, build combos, and chase your best score. Choose how to play with a friend: • Take turns on one phone • Play together on a split screen • Share a room code and play on separate phones Animal Merge battles now continue until your bowl fills, with no drop limit. Both players receive the same animal sequence. Improved game content updates and stability. No account is needed. The interface follows your device language with support for 14 languages. Room-code battles require an internet connection. Includes ads and an optional purchase to remove them. Animal Merge now has personal-best ranks and permanent rewards. Customize your nickname, badge, title and frame, with visibility controls. Track room-battle wins and streaks, add friends and compare personal-best scores. Reset battle records while keeping your best score and unlocked rewards. Two new party games to share on one phone. Secret Feast Ā· 3–8 players Pass the phone and secretly choose one feeding spot. Arrive alone to collect all its points. If two or more choose the same spot, everyone there gets zero. Read your friends and compete for the highest total across rounds. Animal Tower Ā· 2–8 players Take turns choosing a position and tilt, then drop an animal block. If an animal falls below the platform on your turn, you lose. The tower stays still as you pass the phone, then moves again when the next animal touches it or the platform. The original crocodile teeth roulette and Animal Merge are still available.
