You must use actual dice, although the dice don’t have to be six-sided, nor do they all have to be the same size. However, using coins and calling them “two-sided dice” isn’t allowed. We recommend against using four-sided dice for this (except maybe at the top).

The dice must stay stacked for a few seconds after the five seconds have elapsed in order to count. If they’re tipping over as time expires but haven’t quite fallen yet, it’s not a successful stack.

No other player may interfere with your stacking attempt, including shaking the table.

The best stack we ever got was nine dice for five Squirrels. Happy stacking!
