SquareStack

SquareStack is a modern color-matching puzzle game with a unique twist: form a 2×2 square of the same color to trigger a match, and watch as all connected blocks of that color clear in a satisfying chain reaction! Progress through 100 levels with dynamic visual themes that evolve as you advance.

How To Play:

Goal: Clear blocks to progress through increasingly challenging levels. Each level brings new color palettes, faster speeds, and fresh visual aesthetics.

Controls:

Keyboard:

• Arrow Keys (← →) - Move the falling formation left/right
• Up Arrow (↑) - Rotate colors within the formation
• Down Arrow (↓) - Soft drop (faster falling)
• Space Bar - Hard drop (instant placement)

Touch/Mouse:

• Swipe Left/Right - Move formation
• Tap - Rotate colors
• Swipe Down - Hard drop
• Long Press - Soft drop

Match Mechanics:

1. Form a 2×2 square of the same color anywhere on the grid
2. The square acts as a "trigger" - all blocks of that color connected to it will clear
3. Blocks fall and fill gaps, potentially creating chain reactions
4. Longer chains = higher scores!

Tips for Success

• Think ahead - Use the next formation preview to plan your moves
• Create setups - Stack matching colors near each other for bigger clears
• Chain reactions - Let gravity work for you - cascades multiply your score
• Use rotation wisely - The up arrow rotates colors within your formation
