Stacktris Game

Stacktris takes the falling-block shape of Tetris and turns it into a balance test instead of a line-clearing puzzle. Each tetromino spins in place above a small platform, and you have to time when to stop it, slide it into position, and let it drop onto the stack you've already built.

There's no line-clearing here — the only goal is height. A stack that leans too far, or a piece that overhangs the edge, can send blocks tumbling off the platform, and one fallen block ends the run. Pieces spin faster as your tower grows, so the timing window keeps shrinking.

Controls

• Left mouse click (hold): stop the block's spin and drag to position it
• A/D or arrow keys: move the block left or right while it falls
• Release click: drop the block onto the stack
• Esc: menu, Enter: pause
• Touch (mobile): long-press to stop the spin, drag to position, release to drop

Tips

• Center a new block over the stack's balance point rather than always flushing it against one edge
• If the same shape keeps toppling your stack, spend coins earned from runs on upgrades like Wide Table or Low Bounce
• As rotation speeds up, a slightly late stop beats a rushed one — a bad drop costs more height than a short delay

Stacktris suits short, one-more-try sessions — each run only lasts as long as your stack holds together. It's developed by Fancade and playable on both desktop and mobile.
