Jam

1. A block slides along its row or column over free cells, as far as you like, and stops at walls, other blocks and the border.
2. Gates on the border carry a colour and a symbol. A block leaves the tray when it slides into a gate of its own colour that spans its full width.
3. A block can cross the tray and leave in a single slide.
4. Every slide is one move. Clear every block to win.
5. Par is the fewest moves possible: match it without hints for a perfect clear.

1. Slide the blocks. Drag a block along its row or column. It slides over free cells and stops at walls, other blocks and the border.
2. Out through the gates. A block leaves when it slides into a gate with its own colour and symbol that is at least as wide as the block. A quick flick sends it all the way.

• Drag a block along its row or column; a quick flick slides it all the way
• Tab to a block, arrows move between blocks, Enter or Space picks one up, then arrows slide it one cell, Shift and an arrow slide it all the way, Esc puts it down
• H for a hint

Easy trays are 5 by 5 with 4 or 5 blocks in two or three colours. Medium trays are 6 by 6 with 6 or 7 blocks and sometimes a wall. Hard trays hold 8 or 9 blocks and walls on up to 7 by 7, and expert packs 10 to 12 blocks into trays up to 8 by 8. Par is always the fewest slides possible.
