♠ Klondike solitaire
The whole game sits in a single file. Save it and it works with no internet at all — in a cabin, on a plane, anywhere.
Drag and drop, or one tap to move. Hints when you are stuck, undo and redo, night mode and several themes. The sound is generated in the browser as you play. You can draw one card or three, and ask for deals that are actually winnable.

♞ Sjakkmester
A complete chess game with its own engine. No off-the-shelf chess engine involved — it works out its own moves, and the rules are verified against standard positions so castling, en passant and promotion are exactly right.
Play against someone else on the same screen, or against the computer at six levels from beginner to grandmaster. The weakest levels are built to lose in a human way — they miss tactics rather than playing at random, so beating them means something.
New to chess? There are 17 lessons with boards you can click through. As you play, the coach rates every move you make, explains what it achieves and shows what would have been better. Plus hints, undo, a clock, PGN export, a 3D view and six board designs.
