About puzzle.day

Puzzle.day is a brain-training portfolio of 8 daily logic puzzles — Sudoku, Mahjong, Crowns, Nonograms, Kakuro, Loop, Domindle, and Tessera — designed for people who want a calm, ad-free daily routine.

One streak across every game

Solve any difficulty in any of the 12 games and your streak ticks up. Miss a day? Use one of your two monthly streak freezes. Plus subscribers get streak repair + paired friend-streaks.

What's not here

No banner ads. No timed pop-ups. No "buy 5 lives to continue." No streak-loss panic notifications. Accessibility (WCAG 2.2 AA, OpenDyslexic font, reduced-motion, text-size scaling, 5 color palettes) is part of the free tier — Plus only sells decorative, never functional, accessibility.

The only ads we'll ever show are optional rewarded videos you can choose to watch for a one-off perk — unlock a single past-day puzzle, or repair one missed streak day. They're never required, never interrupt a puzzle, and Plus members skip them entirely (the perks are simply included).

Built by

Brent Vincent, with the help of Claude. The four greenfield engines (Balance, Plots, Stars, Loop) are open-source-spirit deterministic generators; the seven imported games (Mahjong, Sudoku, etc.) ship from their original codebases via git subtree.
