Stack Stack: Box Tower

Watch the moving claw, choose your moment, and drop a box. Build your own tower as the boxes tilt, wobble, and settle. Try four difficulty modes, from Easy to Hell, with different platforms and drop heights. Balance standard, short, and tall boxes, preview the next box, and choose a game speed from 1x to 2x. Earn in-game coins to customize boxes, claws, backgrounds, and companions. Save your towers and zoom in to admire them. Your first run includes a free undo. Later, optional rewarded ads can provide an undo or double eligible result coins. Players must be at least 18 and sign in to play. The game includes ads. Gameplay analytics and crash diagnostics are separate, optional choices, off by default; declining either does not prevent play. Complete a rewarded ad in the shop to receive 5 undo tickets. Each undo uses one ticket, and you can use multiple tickets in the same run while you have tickets remaining. Free and ad-supported undos have separate eligibility limits. Take on 100 achievements and choose your next goal. Use Cloud save in Settings or History to manually back up your towers, coins, tickets, cosmetics, and achievements to your own account and import them on another device. Progress does not sync automatically, and currency balances are not added together.
