About
A fresh take on falling-block puzzles: every block that drops is a √ (square root).
Drop a √ onto another √ to multiply them. When an integer can be extracted, the result splits into an integer below and the remaining √ above. Matching integers connected horizontally or vertically merge into a power block. Two 3s make 3²; add another 3 to make 3³… Keep the chain going to grow bigger numbers.
FEATURES
• Simple rules built around √, with deep number strategy
• Your score is revealed at game over, with a breakdown of how many points each number earned
