Stack falling blocks to build the tallest tower! Time your drops perfectly to earn combo bonuses and beat your high score in this addictive stacking challenge.
How to Play:
Blocks slide back and forth across the screen. Click, tap, or press Space to drop each block onto the growing tower. The block must overlap with the one below it — any excess width is cut off. Stack as high as you can!
Objective:
Build the tallest tower possible by stacking blocks with increasing precision as they get narrower.
Controls:
- Desktop: Click on the canvas or press Space to drop the block
- Mobile / Tablet: Tap the canvas to drop the block
Scoring:
- Overlap width points per block — wider overlaps earn more points
- Perfect placement bonus: Align within 98% of the block below for bonus points and a combo multiplier
- Combo streak: Consecutive perfect drops multiply your score
- Speed increases every 5 blocks, making precision harder
Winning:
- Win: There is no win condition — this is an endless stacking game where the goal is to achieve the highest score
- Lose: The block misses the one below entirely — the tower ends and your final score is displayed
Difficulty Levels:
- Easy: Slow-moving blocks (speed 2) with a wide starting width (110px) — relaxed stacking with plenty of time
- Medium: Moderate speed (3.5) and medium starting width (85px) — the standard stacking challenge
- Hard: Fast-moving blocks (speed 5.5) with a narrow starting width (65px) — rapid precision stacking
Game Features:
- Alternating direction — blocks enter from left and right alternately, keeping you on your toes
- Cutting mechanic — any excess width beyond the block below is trimmed, making towers progressively narrower
- Perfect placement detection — near-perfect alignment triggers bonus points and combo multipliers
- Combo system — consecutive perfect drops build your multiplier for massive score potential
- Increasing speed — blocks move faster every 5 blocks, ramping up the challenge
- 8 vibrant block colors — cycling neon color palette as the tower grows
- Camera follow — the view smoothly tracks upward as your tower climbs
- Particle effects — satisfying particles burst on each block placement
- High score tracking saved to localStorage
- Floating score text — points appear at each drop location
Pro Tips:
- Wait for the perfect moment — don't rush, time your drop when the block is perfectly aligned
- Chase perfect placements — the combo multiplier from consecutive perfect drops can massively boost your score
- Watch the speed ramp — every 5 blocks the blocks move faster, so practice your timing early
- Accept small imperfections — if you miss the perfect window, drop early rather than waiting too long
- Focus on consistency — steady, well-timed drops beat frantic clicking every time
