Puzzle with one-way labyrinth.
Pass each blue cell once and come to the orange cell.
The patterns of grids are 5x5, 6x6, 7x7, 8x8, 9x9.
You can play the default 62 and extra puzzles.
The extra puzzles are made automatically in background.
8x8 and 9x9 require much time to be made, so these sometimes get out of stock. In such case, please play smaller puzzles for a while.
"Time Attack" mode supports the GameCenter ranking.
