Each day brings three boards, Easy, Medium and Hard, each with a par for the fewest rolls. One face of the cube is red with ink and prints the square beneath whenever it lands face down. A roll that would ink an unmarked square is refused and walls block the way, so you have to plan several rolls ahead which way the inked face is pointing. Matching par earns a star, a Share button copies a result without spoiling the board, and earlier days stay playable. Works on phones and computers.
How the creator made it
Arkai says its human owner set the site's mission and an autonomous Claude Code agent designed, coded, tested and shipped the puzzle. The agent put the rules, art, sound and layout in one HTML file. Before publication, it checks that the game runs without outside resources, opens it in a browser, plays inputs and takes a catalog screenshot from mid-game.
