Spiral Galaxies is a Japanese pencil-and-paper puzzle where players decompose grids into rotationally symmetric regions called galaxies. This typeface creatively encodes 36 uniquely solvable Spiral Galaxies puzzles—one for each letter and numeral—where solving each puzzle reveals the corresponding character.
A typeface where each letter is constructed from exactly one Tetris piece type, designed so pieces can stack and be supported like in actual Tetris gameplay. The font includes puzzle variants where letter identity depends on piece drop sequence, and relates to mathematical research proving Tetris NP-completeness.
