The crane hoists a block over the roof, ready to release with a single touch. If you place it right in the middle, the tower rises steadily and boosts your combo. But if you miss by even a little, the floor will be skewed and the imbalance will accumulate.
Each block might be a lucky one, and you'll know its effect only after it lands. Spikes reduce the landing zone for the next level, a slab expands it, a tornado adds movement, a coin grants points, and a heart restores a life.
The tower behaves realistically — it collapses due to instability, not height. Keep an eye on the stability bar and correct the stack before it's too late.
Rings on the tower represent your personal record and the closest rival from the leaderboard. Surpass one and the next player becomes your new target.
You can exit at any time — the tower will be saved in its current state, including any lean, and the menu will offer to continue.
How to play
To manage everything, use a single control: click the mouse, press the spacebar, or touch the screen to drop the block.
Aim for the green area on the roof. Hitting the centre is considered perfect and helps build a combo: each consecutive perfect landing increases the score, up to eight times. A miss resets the combo.
If you miss the tower, you lose a life. You have three lives, and a heart from a lucky block will give you one back.
The stability bar at the bottom shows how much the centre of mass has shifted beyond the base. If it turns red, place the next blocks on the opposite side to keep the stack straight. If the shift is too great, the tower will collapse.
Press Esc or the corner button to open the pause menu. Leaving from there saves your progress: you can return and continue from the same floor.
