Gridline

Gridline is a block puzzle with 9x9 solo modes and tactical AI duels on side-by-side 6x9 boards. Place shapes, complete rows, columns, and 3x3 boxes, clear the board, survive rising pressure, and outplay opponents in versus matches. Easy to learn, hard to put down.

Five game modes:

Classic
A clean, focused puzzle mode. No helpers, no gimmicks, just you, the grid, and better decisions every turn.

Boost
When a run starts going bad, use power-ups to recover:
• Swap — replace any piece with a new random one
• Reshuffle — get a fresh set of all three pieces
• Erase — remove any single cell from the board

Pressure Line
The board fights back. Every few moves, a row of gray blocks rises from below. Keep clearing lines or run out of space. Includes all Boost power-ups.

Rush Line
Pressure Line with timed missions. Clear rows, build combos, and use Freeze to stop the clock when every second matters.

Duel
Gridline's standout versus mode. Face AI opponents on two side-by-side 6x9 boards, build your own score, and disrupt the other side at the right moment. Three difficulty levels, from relaxed to ruthless.
