Halcyon: Mahjong Solitaire

Halcyon is a calm game of mahjong solitaire. Match pairs, clear the board, unwind — with the game's own illustrated tiles, or tiles made from photographs of your own.

EVERY BOARD CAN BE FINISHED
Each board is built so that it can always be cleared. If you get stuck, it is the order of your moves, not the deal. Hint points out a pair you can take right now, Undo takes back your last move, and Shuffle re-deals what is left into a fresh layout you can finish.

PLAY IT YOUR WAY
• Quick boards for a few minutes, Standard boards for a coffee, Evening boards for a long sit
• Gentle, Standard or Tricky dealing — difficulty changes how far apart the pairs land, not the shape of the board
• Classic layouts, plus 10,000 numbered boards you can return to by number or share with a friend
• Surprise Me picks a board, a set and a background for you

YOUR PHOTOS AS TILES
Choose twelve or more photos, crop each one to the tile, and play any board with them. Photos are chosen through Android's photo picker, so Halcyon never sees your library — only the pictures you pick. They are copied into the app on your device and never uploaded. A sample set is included so you can see how it plays.

ONE BOARD A DAY, THE SAME FOR EVERYONE
The Daily Board is replaced at midnight and is identical on every phone. Play on consecutive days to build a streak: three days earns a Free Pack Pass that opens any locked pack for twenty-four hours, and every twenty-eighth day earns a pack to keep. Missing a day is forgiven once a month, automatically. On some days a locked pack is lent to you for the daily, for nothing.

TWENTY-EIGHT ILLUSTRATED PACKS
Every pack is a set of tiles, its own backgrounds and tile styles, and its own music, all made for Halcyon — no stock art, no licensed audio. Bento and Bodega Cat, Cryptid Field Guide and Goblincore, Moon & Dagger and Neon Horizon, Origami, Stained Glass, The Orchestra, Best in Show, The Ski Lodge and many more. Three illustrated sets are yours from the start, and more are earned as you level up. Packs are $2.99 each, or unlock everything — including every future pack — with the Complete Collection. Not sure about a pack? Try it for one full game by watching a short ad, and keep playing your own boards without ever seeing one.

MADE TO BE QUIET
• No account, no sign-in
• Ads only when you ask for one, and never personalised
• Light and dark appearance, a reduce-motion option, and haptics you can turn off
• Plays in portrait and landscape, on phones and tablets
• Optional daily reminder — one quiet notification, only on a day you have not played

Recent changes:
If a move leaves the board impossible to clear, Halcyon now says so right away and offers to undo back to the last point where it could still be finished. Hint keeps pointing to a pair that leads to a finish even after you have strayed from the dealt order, and new players start on Gentle dealing.

The Privacy screen now lists everything Halcyon counts, including boards left unfinished and visits to the store, so we can see where new players get stuck.
