Why does every solitaire app bury a simple deck of cards under ads, coins, streaks, and spinning prize wheels? This is just solitaire. • Classic Klondike — draw one or draw three • Crisp 8-bit pixel art on a clean, dark table • No ads. Ever. • No account, no tracking, no notifications begging you to come back • Nothing to buy — everything's included BUILT FOR ONE HAND • The whole board sits mid-screen, right where your thumb lives — no stretching to the top corners • Left- and right-handed layouts: the deck, pause, and undo all flip to your side • Tap to move — no fiddly dragging. One tap sends a card where it should go. MAKE IT YOURS • Difficulty modifiers: draw three, kings-only empty columns, locked foundations, undo on or off — stricter rules multiply your score • Winnable-deals-only mode, or gamble on a true random shuffle • Dead-end detection calls the game the moment it can't be won — no wasting time on an unwinnable deal THE DETAILS • Undo, restart a deal, auto-finish a won game • Local top-10 scores with time and difficulty • Fireworks when you win. The cards drip off the table when you lose. No missions. No coins. No timers. Just a good-looking deck of cards.
