How to play Speed Math

You start with a number and need to reach the target. You have a set of operations (like +5, ×3, −2) that you can apply in any order. Each tap applies an operation to your current number. The goal is to reach the target in the fewest steps possible.

Star rating: ⭐⭐⭐ if you match the optimal solution, ⭐⭐ if you're one step over, ⭐ if you solve it in more steps. Every puzzle is guaranteed to be solvable!

Tips for chain puzzles

  • Multiplication gets you to large numbers fast — use it early if the target is big
  • Work backward mentally: what operation would make the target from a nearby number?
  • Don't be afraid to undo — finding the optimal path sometimes requires backtracking
  • Easy mode uses only addition and subtraction. Medium adds multiplication. Hard adds division.

About this game

Speed Math is a novel chain-path puzzle. Unlike calculators that just compute answers, this game asks you to find the shortest PATH through a series of operations. Each puzzle has a guaranteed optimal solution, and often multiple valid paths exist.
