Tintail

Tintail is a calm, turn-based snake puzzle about coats of dye. Every sand tile needs an exact number of coats, shown as pips, and each step of the snake's head lays one. When a tile has all its coats it glazes and becomes a wall. You can never step into your own body, so a tile can take its next coat only once your whole body has left it: a short snake loops back quickly, a long one needs a wide circle. Berries make you longer, shells make you shorter, and grey stones can be crossed as often as you like. Glaze 24 islands in four archipelagos for up to three stars each, take on the daily island that is the same for everyone, or see how far the endless islands go. Undo is unlimited, and a hint shows the next step or how far to undo, so you are never stuck. It plays in the browser with a keyboard, mouse, touch or gamepad.
