Shut the Box Online

Shut the Box online is the classic pub dice game, playable free in your browser with nothing to download. Roll two dice, then flip any combination of numbered tiles that adds up to your roll. Keep going until no legal move remains — shut every tile and you have shut the box.

How to actually win. The tiles are not equally valuable: the high ones (7, 8, 9) are the hardest to clear, because once you are down to one die they become unreachable. Clear them early while you still have two dice and a wide range of sums. Beginners burn their low tiles first because those rolls come up more often, then get stranded with an 8 they can never make.

When you can split, think ahead. A roll of 9 can be taken as 9, or 5+4, or 6+3, or 7+2. Prefer whichever combination leaves you the most flexible board. Two mid tiles usually beat one high tile early on, but late in the game clearing the single highest remaining tile is almost always right.

Once tiles 7, 8 and 9 are down, most rule sets let you roll a single die, which changes the maths completely — from then on you can only make 1 through 6, so anything left above 6 is dead. Plan for that moment before it arrives.

The game is known by a few names — close the box, canoga, batten down the hatches — and has been played in British pubs for generations. It is also a genuinely good way for kids to practise mental addition without it feeling like homework, which is why it earns its place here.
