A closer look at this board
The circle has 4 legal forward openings. There are 2 inactive squares inside the occupied rectangle; plan how to connect the areas around them. Filling an area too early can leave another area disconnected. A full path must cover every active square before the diamond.
Show a verified opening tip
One verified opening moves from the circle at row 4, column 6 to row 4, column 7. Keep the diamond at row 7, column 4 for the final move. A missing square near row 3, column 3 breaks a row. Check the connections above and below before committing to a side.
Controls and recovery
Drag or tap neighboring squares; arrow keys also work. Retrace the immediately preceding square to undo, or press Backspace. Restart resets only this board's current route. No automatic warning appears while you can advance; a stationary stuck head gets a general nudge after about three seconds. Manual Hint provides up to 3 next-square hints per level. Rechecking a previously hinted route position is free; When device storage is available, Undo, Restart and refresh do not refill the allowance. If saving is blocked, used hints last only for this visit. General stuck reminders are free.
