Frequently Asked Questions

Click on the game screen or press SPACE bar to place the moving block. Stack each block perfectly on top of the previous one. The better you align, the higher your score!

When you place a block that aligns almost perfectly with the block below, you get a 'Perfect!' bonus. This gives you extra points and increases your combo streak.

Each block gives you 10 points. If you get a perfect placement, you earn bonus points: 1st perfect = +5, 2nd = +10, 3rd = +15, 4th = +20, 5th = +25. Higher combo = more points!

Combo counts consecutive perfect placements. Each perfect adds to your combo (up to 5x). If you miss a perfect, combo resets to zero. Higher combo means bigger bonuses!

Every 5 blocks you level up! The block moves faster and perfect placements become harder to achieve.

Three achievements to unlock: 10 BLOCKS! (Stack 10 blocks), LEVEL 5! (Reach level 5), PERFECT 5X! (Get 5 perfect placements in a row).

If the moving block doesn't overlap with the tower at all, the game ends. Your final score is shown, and if it beats your previous best, your high score is saved automatically!
