Stack Tower Insanity

How high can you stack before the tower fights back? Stack Tower Insanity starts as the stacking game you know — tap to drop blocks, land them perfectly to keep your tower wide — and turns into something else entirely the higher you climb. STACK Tap to drop moving blocks. Perfect drops keep your block wide and build a scoring streak: land them back to back and each one is worth more than the last. Miss the edge and your tower shrinks until there's nothing left to land on. SURVIVE THE SWAY From floor 25 every block is worth double — and the whole tower starts swaying. Timing gets harder, drops get riskier, and every perfect landing matters. FIGHT BACK Reach floor 50 and the game transforms: your block becomes a ship. Steer with tilt controls, auto-fire at incoming enemies, and survive as long as you can. The invasion starts as a trickle and builds to a storm by floor 100 — and a drop timer keeps you climbing, so camping is never an option. BOSSES Every tenth enemy is a boss: twice the size, ten times the health, and a gun that sprays the whole lane. Bring one down for a serious score. GRAB THE POWER-UPS Downed enemies drop shields, rapid fire, and screen-clearing bombs. Steer into them mid-fight to turn a losing run around. UPGRADE YOUR SHIP Spend coins on fire rate, damage and hull upgrades — then max them out to unlock TWIN CANNONS and fire two shots at once. CLIMB THE LEADERBOARD Daily, weekly and all-time boards.
