Shut the Box Strategy and Tips

Here is how to think about winning at Shut the Box, split into short lessons. Each one reads on its own, and each one comes with a real position: press Try it on the board and you play the move yourself.

Close the big tiles first

Lesson 1

Your score is the total of the tiles still open, and lower is better — close all nine and you win on the spot. The damage comes from the big numbers: a lone 9 costs nine points, and 8 with 9 costs seventeen. Clearing the big tiles while you can is the most reliable way to keep your score down.

Here the roll total is 9, so you can close the single 9 or the pair 4 and 5. Spending 4 and 5 leaves the 9 sitting there, and unless an exact 9 turns up again it is locked into your score. Closing the 9 leaves only two small tiles behind.

Big tiles can only be closed when the roll matches them exactly, so take the chance when it comes even if it closes fewer tiles. Small tiles can be recombined in many ways, so leaving them for later costs you very little.

Keep the small tiles

Lesson 2

The mirror image of clearing the big tiles is keeping the small ones. Tiles 1 and 2 work on their own and also top up any other tile to an exact total. Simply holding them widens the range of rolls you can still answer.

The total here is 3, so you can close the single 3 or the pair 1 and 2. Spending 1 and 2 leaves 3, 7 and 9, which only answers rolls of 3, 7, 9, 10 and 12. Closing the 3 leaves 1, 2, 7 and 9, which covers nearly every total from 2 to 12.

Closing more tiles at once looks like progress, but only the tiles left open ever score. Given the same total, pick the combination that leaves you the most answers for the next roll.

Play the odds around seven

Lesson 3

Two dice are not evenly spread. A total of 7 comes up in six of the thirty-six outcomes, more than any other, with 6 and 8 close behind at five each, while 2 and 12 appear just once. Use that bias when you choose which tiles to spend.

The total here is 7, and both 1 with 6 and 2 with 5 will close it. Closing 1 and 6 leaves 2, 5 and 9, and since 2 plus 5 makes 7 you can still answer the most likely roll. Closing 2 and 5 leaves 1, 6 and 9, where making 7 needs both remaining small tiles.

Whenever the choice is unclear, check whether the tiles you would keep can still build 6, 7 or 8. If they can, your round is far more likely to continue.

Switch to a single die

Lesson 4

Once 7, 8 and 9 are all closed you may roll a single die, and the condition can be changed in the settings. Two dice can never total less than 2 and usually land near 7, which overshoots a board that only has small tiles left.

Here just 2 and 3 are open. With two dice only totals of 2, 3 and 5 do anything, which is seven outcomes out of thirty-six, so most rolls are dead. With one die, 2 closes tile 2, 3 closes tile 3, and 5 closes both. Three of the six faces let you continue.

Whenever the single die is available, the smaller your open total, the better it is. Stay on two dice only while a large total is still needed to clear a tile.
