Mastermind Classic vs Midnight Mahjong Solitaire

Mastermind is a code-breaking game for one player. It is based on Mastermind, one of the most popular logic games in history. Its rules are also closely related to the classic game Bulls and Cows, originally played with pencil and paper. This version features three difficulty levels, so the game can grow with you. You can learn how to play in less than 5 minutes. You are the code breaker, and your goal is to discover the secret combination of 4, 5, or 6 colors. After every attempt, you receive clues that help you improve your next guess: 1. Green Key Peg – one of your pegs has the correct color and is in the correct position. 2. Highlighted key peg – one of your pegs has the correct color, but it is in the wrong position. 3. No Key Peg – the color does not appear in the secret code.

A calm mahjong solitaire for the end of the day. No forced timers, no lives to run out — just moonlit tiles and a board to clear at your own pace, with a guaranteed win path on Easy or real risk on Hard. Match pairs across five classic layouts — Turtle, Dragon, Fortress, and more. Choose from five tile skins, each hand-drawn with authentic Mahjong glyphs, and unwind to a calm Chinese-instrument soundtrack. Play fully offline, with hints and undo when you need them. A quiet way to unwind, wherever you are. HOW IT PLAYS • Tap a "free" tile (not covered, not hemmed in on both sides) to select it • Tap its matching pair to clear both • Stuck? Reshuffle the remaining tiles, or use a Hint to reveal a valid pair • A board is won when every tile is cleared WHAT YOU GET • Five board layouts — Turtle, Pyramid, Dragon, Cross, Fortress • Three board sizes — S (80 tiles), M (112), or L (144, the full classic board) • Two difficulty modes — Easy always deals a board with a path through; Hard drops that guarantee • Five tile themes — Ivory Classic, Lacquer & Gold, Nature Illustrated, Mother-of-Pearl, Blue Porcelain — each restyles the whole app, with real Mahjong glyphs (numerals, winds, dragons, flowers, seasons), not generic icons • Unlimited undo — take back a match or a reshuffle any time, no penalty • A live timer and move counter, toggleable in Settings • Optional ambient music and tile-click sound, independent toggles • Pinch to zoom and drag to pan, so the densest boards stay readable • A daily play streak — win one board a day to keep it going, with achievements unlocking as it grows, and an optional evening reminder • Per-layout stats — best times and win streaks for each of the five board layouts RELAX AND THINK No fail states, no forced ads mid-board. Just the tiles, the timer if you want it, and that satisfying moment when the last pair clears. WHAT'S FREE, WHAT'S PAID Two layouts and two tile themes are free to play, ad-supported.
