Merge Beast Arena

Merge Beast Arena is an idle merge game and auto-battler in one. Start with a tiny mouse and tap it for coins — then drag two identical animals together to merge them into something bigger. Rabbit, cat, fox, wolf, bear, gorilla, lion, tiger, elephant, rhino, crocodile, shark, orca, whale, T-Rex, dragon: 19 beasts climb the food chain, each one visibly larger and far stronger than the last. And if you merge two dragons, you awaken the magma boss — a tier-20 monster that one-shots anything it touches.
