How to play

Swap tiles until every full row and column contains the numbers 1 to 7, each exactly once.

• Drag a tile onto another to swap them, or tap one and then another.
• Tiles turn this colour when they're in the right place, and are then locked.
• Tags in the gaps show the sum of the two tiles their arrows point to: one to the side and one above or below. No tile is pointed at twice. A tag showing 10 that points to a 4 and one unknown tile means the unknown is 6.
• Try to finish within 20 swaps. Every puzzle can be solved in 15, and each swap you have left earns a ★. If you run out, keep going; you just won't earn stars.
• Swapped the wrong tiles? Press Undo within 2.5 seconds to reverse the swap and get it back. Shortcut: Ctrl+Z or U.
• Prefer different colours? The settings button has other schemes, including ones for colour blindness.
• There's no daily limit, so play as many puzzles as you like.
