Reverse Calculator

简介

Exercise your brain (and fingers!) in Reverse Calculator. Each game is 2 minutes of creating expressions which match the number boxes. While simple expressions can be used, to get high scores one must use difficult expressions to stack combo bonuses.

玩法说明

Simply enter expressions into the input box. The solution of each expression is checked with all 8 of the number boxes.

Any useless brackets / leading zeros / double negatives are automatically removed from the expression before it is matched with the number boxes.

Boxes with yellow borders are timed and disappear after a while. Boxes may have restrictions on the expressions which can match it, indicated by the red text above the number. Matching boxes with smaller ranges gives more score.

The difficulty influences the magnitude of the numbers/ranges, and increases the chance of boxes with restrictions.

Note: All values are integers, so for instance, 8/3 = 2.

Available Combos:
Same Digit Combo (All digits identical in expression with 4+ digits)
Same Operator Combo (All operators identical in expression with 3+ operators)
Distinct Digit Combo (All digits distinct in expression with 6+ digits)
Distinct Operator Combo (All operators distinct in expression with 3+ operators)
Bonus Character Combo (Bonus character used in expression)
