How to play

• Tap a tile, then tap another. Everything between them reverses, ends included.
• You can also drag from one tile to another.
• Sort the row 1 to 8, left to right.
• Linked neighbors are joined by a bar. The walls at each end count too.
• Best possible is the fewest flips that can sort today's row. Every flip counts.
• A new row arrives at midnight.
