The whole game lives in a clip on case that fits a jacket pocket: five dice, a scorepad and an everlasting pencil that never needs sharpening. Roll and re-roll to chase set combinations, then score them on the pad. With one player it is a race against your own best round; with a table full it is the fastest thing you can start after dinner.

The case is rated IPX5 against water jets and shuts with a locking clip, and the carabiner clips it to a belt loop, a pack strap or a tent zip. That is the whole idea. This is the game that still works on a rained out campsite, in a boat, or at the bottom of a beach bag. Kikkerland made it with Goodlines.
