Prisma Sudoku - Ad-free, offline Sudoku that rewards every solve
A calm, minimalist Sudoku for iPhone — completely free, no ads, no subscription, no account. Four difficulties and a daily puzzle, fully offline. Every solved puzzle charges a glowing artifact (36 to collect) that lights up your own constellation.
