Drag the pieces from the tray below onto the board. No rotating.

Fill a whole row or column and it clears.

Every clear tips the tray and every tile slides that way. The yellow arrow on the rim shows the next direction — plan around it.

As it tips, loose tiles roll in from the raised edge. The slide is never free.

If the slide completes another line you get a chain, and the score multiplies. This is where the game lives.

The bolted anchor tiles never slide. Everything else piles up against them. Clear one and it pays well.
