NOT A TETRIS CLONE — NO TETROMINOES, NO ROTATION.
A single coloured cell descends a 4 × 12 well. Landing it connects lines of 3 or more same-coloured cells — horizontal, vertical, or diagonal — which clear, collapse under gravity, and can chain into multi-step cascades.

How to Play

• Match 3 or More: Align 3+ cells of the same color/glyph down, across, or diagonally.
• Gravity & Cascades: When a line clears, any floating cells directly above collapse downward. If newly settled cells form new lines, they automatically clear as a Cascade with compounding score multipliers.
• Level Progression: Every 45 cleared cells advances the game to the next level, steadily increasing the fall speed from Level 1 up to Level 21.
