Learn the rules, modes, and tips for mastering the game.

🎯 Objective

Place pieces on a 10×10 board to complete full rows or columns. Clearing lines gives you points. In Timed mode, clear lines with golden bonus cells to earn extra seconds.

🎮 Game Modes

  • Classic Endless play; focus on score and combos.
  • Timed Start with 300s. Clear golden bonus cells to add +10–60s each.

🧩 Controls

  • Drag a piece from the tray below and drop it on valid cells.
  • Pieces can't overlap or go out of bounds.
  • Fill an entire row/column to clear it and score points.

✨ Bonus Cells (Timed)

Every 60 seconds, 3 golden bonus cells appear on the board. If you clear a line that includes them, you gain the cell's value (+10 to +60 seconds each).

  • Bonus cells don't block placement.
  • Multiple bonus cells in one clear stack together.
