Klondike, Spider, Yukon: 10 Solitaires in One

Ten classic solitaire games in one: Klondike, Spider, FreeCell, Yukon, Scorpion, Canfield, Forty Thieves, Pyramid, TriPeaks and Golf. The rules are yours to pick before the deal. Klondike deals one card or three, with or without a limit on passes through the stock. Spider runs on one suit, two, or all four. It plays with one finger. A tap sends a card where it belongs, a long run moves by dragging. Five hints per game, undo for any move, and a "Collect all" button at the end. If no moves are left, the game says so. Every day brings a new daily deal, the same one for every player. Days in a row build a streak, and the calendar shows the gaps. Thirty-three achievements, per-game statistics, card backs and felt colours to unlock. No sign-up, no install: open it and play. The game weighs about a hundred kilobytes, so it starts even on a slow phone.
