Daily Challenge
The Daily Challenge is a single shared Mahjong Solitaire board that resets every calendar day at midnight UTC. Everyone worldwide sees the same tile arrangement, the same hidden pairs, and the same puzzle to solve — so you can compare times with friends or treat each day like a lightweight speedrun stage without needing accounts or leaderboards.
We always use the classic Turtle layout for the daily board: it is the most recognizable Mahjong Solitaire shape, the fairest common benchmark, and the easiest layout to discuss when you are swapping strategy tips. If you want Dragon or Pyramid instead, use the home page or the Dragon and Pyramid routes — only the Daily Challenge is locked to Turtle for consistency.
How the daily seed works
The generator pairs the full tile pool, shuffles pairs, and places the first 72 pairs on the board while dropping six random pairs unseen — the same rules as our other layouts. The only difference is the seed: it is derived from the UTC date, so the puzzle is deterministic for that day and changes predictably when the clock rolls over. Refreshing the page will not reroll the board; clearing site data and revisiting on the same UTC day still reconstructs the same arrangement.
Rules, hints, and scoring
Matching rules follow Mahjong Temple everywhere: seasons are wildcards within the season group, flowers require exact pairs, and all numbered suits need identical suit and rank. A tile is free when nothing sits on top of it and at least one lateral side is open. You have three hint uses per daily run; each hint highlights a legal pair when one exists. Shuffling remaining tiles is allowed if you get stuck, but it adds thirty seconds to your elapsed time so it is a deliberate trade. Undo is unlimited and simply walks back moves, which also keeps the experience approachable when you mis-click.
