Dot to Dot

Draw one line from 1 to the last number. It cannot cross itself, and it cannot go through a wall.

Drag along the grid, or tap the next cell. Tap a cell the line has been through to go back to it. Undo takes back your last stroke, and Reset takes the line back to 1. On a keyboard the arrow keys draw and Backspace goes back a cell.

Everyone gets the same puzzle, and a new one arrives at midnight. A puzzle solved is 500 points. A hint draws the line as far as the next number and costs 100, and a solve is never worth less than 100. The clock starts when you press Play and Reset does not stop it. Among players with the same points, the faster time is ahead.
