17,723 classic and 206 mini equations, generated from the rules

Only here Generates every possible equation from the rules (17,723 classic, matching the game) and ranks your next guess by how much it narrows them down.

Enter the equations you've played and set each tile's colour. You'll get the equation that narrows things down the most, out of every one that could still be the answer.

Add the equation you played, then tap each tile until it matches: grey, purple (in the equation elsewhere), green (right spot).

How it works

We generate every equation the puzzle allows: digits and + − × ÷, one "=", a whole-number answer on the right, the usual order of operations, and no leading zeros (a lone "0" isn't allowed). Fractions are fine partway through, as long as the answer is whole. Those rules give exactly 17,723 classic and 206 mini equations, the same totals the game's own count gives, which is how we know the rules are right.

Each suggestion is scored by its expected information (Shannon entropy) over the equations still possible. With every equation scored, the best classic opener is 48-32=16 and the best mini opener is 4*7=28.
