This is virtual math dice. You can play the game without having the dice. Use the four operations (+, -, *, and /) and exponents on the three numbers to get as close as you can to the target number. The game does not calculate the best answer; it only rolls the dice and gives you a target to work toward. Pre s. Press 'r' to reset the built-in twenty second timer.
