Curvy is a satisfyingly simple HTML5-based game where you twist a board full of hexagons in order to make each hex's lines and curves connect properly. You can customize the board layout and complexity, and take your time as you solve each Zen-like puzzle, making each piece fit as you bring order out of chaos.

Choo Choo Puzzles, the new simple idea dragging puzzle from a team led by Piotr Iwanicki, sounds like a cross between a candy bar and a maze you'd find in Highlights for Children... kind of inappropriate for a fun little game with only a tenuously abstract connection to railways. Fortunately, the simple mechanics of Choo Choo Puzzles present a worthy challenge for puzzle-lovers of all ages.

Hex Empire is a casual turn-based strategy war game, occupying a comfortable spot between the simplicity of Risk and the number crunching of the Avalon Hill-style board games that inspired the whole soldiers-on-hexagons thing. It lets you jump right into battle without much fuss, and offers enough tactical depth to be addictive even after several wars have ended. A bit of a treat, really.
