Select open numbers that add up to the dice. Lower final score wins.
One die unlocks after every tile above 6 is closed.
Retry repeats this dice sequence. New dice starts a fresh sequence. No undo after a reveal.
Shut the Box turns addition into a sequence of choices. A total of 8 might close 8 alone, 3+5 or 1+2+5; each leaves a different future board.
This original browser version offers 9/12-tile boards, optional one-die play, all legal combinations on request, same-sequence practice and fair local two-player rounds.
Choose nine tiles for a shorter round or twelve for more high-number decisions. Each new sequence offers fresh decisions; there are no numbered levels.
Two-player uses the same pair at each roll index. Choosing one die can change the total. Retry lets you compare different closures on the same sequence; New dice changes it.
For a total of 8, closing 8 removes a difficult high tile. Closing 3+5 instead preserves 8 but changes your small-number combinations. Neither choice guarantees a shut box.
After 7 and above are closed, one die can make 1 and avoids totals above 6. Two dice still offer different combinations. Check what your remaining numbers can make.
Even a careful round may end with points. Retry the same sequence to study a decision, or start new dice for an independent round.
No. These are repeatable dice-and-combination rounds with 9 or 12 tiles, not numbered levels.
Yes, take turns on the same device. This version uses one device and has no online rooms.
A round with numbers remaining is a normal scored finish. A lower score is better; only zero shuts the box.
The sum of remaining numbers. This is not the concatenated-number variant. A 1 and a 9 left open score 10, not 19.
Only after every tile from 7 through 12 is closed. It remains optional.
No. You choose every closure. The combination list gives legal options; it does not pick a move or claim a perfect strategy.
