Place blocks on the 8×8 grid to fill complete rows or columns. Completed lines are cleared and earn Gold, Power and XP. The game ends when none of your 3 pieces can fit anywhere.

Tap a piece in the tray to select it (glows green). Then tap the grid to place it. A coloured preview shows where it will land.

Tap the same piece again to rotate it 90° clockwise. Or tap the ↻ ROTATE button. Cycle through 0° → 90° → 180° → 270°.

Desktop: 1/2/3 selects a piece · R rotates · Esc deselects · ? opens help.

1 line cleared: 100 pts × combo × level multiplier

2 lines at once — DOUBLE CLEAR: combo increases, bonus gold

3+ lines — MEGA CLEAR: massive bonus, combo jumps

Chain clears to build your combo multiplier up to ×8. Place a piece without clearing and it resets to ×1.

Gold — earned by clearing lines. Spend on abilities and building upgrades.

Power — trickles in from your Reactor building every few seconds. Required for upgrades alongside Gold.

XP — accumulates as you play, tracking your long-term progress.

Strike (50⚡) — clears a random filled row instantly

Storm (40⚡) — activates 15 seconds of chaos: every piece you place slides a random row left or right, and every line you clear triggers a gravity collapse of another row — chain reactions possible!

Drone (80⚡) — clears one row AND one column at once

Nuke (200⚡) — wipes an entire 4×4 quadrant of the grid

Spend Gold + Power to upgrade your 6 buildings. Upgrade the Reactor first — it increases your Power trickle rate, which unlocks faster upgrades across the board.

Each rank unlocks more block colours and increases the score multiplier. Higher levels are tougher — more colour variety means harder planning.
