About

Crab Tower

Read full description

One more crab. One tricky balancing act. Crab Tower is a single-player physics stacking game where every drop changes the balance. Build a tower of crabs on a boat-shaped platform and chase a new high score. Easy to start, tricky to keep steady. DRAG, TAP, STACK Drag to line up your next drop, then tap to release. Find a steady spot for each crab and keep your tower standing. Play a quick round during a break or take your time chasing a personal best. SIX TYPES, UNPREDICTABLE TOWERS Stack crayfish, swimming crabs, hairy crabs, lobsters, king crabs and the rare golden crab. Different shapes, values and chances of appearing make each round a fresh balancing challenge. A GOLDEN CHANCE AT A HIGHER SCORE Your score is the total value of the crabs you stack. If a crab falls, its value is deducted. Think beyond height: a well-balanced tower is the key to protecting your score. PLAY YOUR WAY Choose from five music tracks or turn the music off. Sound effects have their own on/off setting. Available in 10 languages. Can your tower hold one more crab? Displayed amounts are in-game scores, not real money. No cash rewards or withdrawals.
