Mathler's Expanded Puzzle Library

We've expanded Mathler's puzzle library with thousands of new equations across all difficulty levels. Here's what's changing and why.

Why We Did This

Mathler launched with a curated set of around 275 puzzles per difficulty level. These puzzles were hand-picked to be fun and fair, but with daily play, the pool would eventually cycle through.

We've now grown that library significantly—over 16,000 total puzzles across all four difficulty levels—while maintaining the same quality standards that made the original puzzles enjoyable.

What Makes a Good Mathler Puzzle?

Not every valid equation makes for a fun puzzle. Our puzzle selection filters out equations that would be frustrating or too easy to guess:

  • No trivial operations — We exclude equations with ×1, /1, +0, -0, or ×0. Every operation should matter.
  • No repeated terms — Equations like 86/86 aren't interesting to solve.
  • Reasonable factors — Division puzzles use factors you can reasonably deduce, not obscure primes.
  • Balanced results — We avoid target numbers that have too many possible solutions, which turns solving into guessing.

What's New by Level

Easy (5 characters)

More variety in simple two-number operations. We've reduced puzzles where the target number has dozens of possible factor combinations, making solutions feel more earnable.

Examples: 85-32, 84/42, 44+18

Normal (6 characters)

A broader mix of equation structures, with more patterns that give you useful information as you guess. Division-leading patterns like 42/7+5 now appear more frequently alongside multiplication patterns like 21*4-5.

Examples: 42/7+5, 63/9-1, 13*5+4

Hard (8 characters)

Significantly more parentheses patterns. The original set had around 40 different equation structures; the new library has 34 focused patterns with much more variety in how parentheses are used.

New patterns you'll see:

  • 76*(8+7) — multiplication with parentheses on the right
  • (12-3)*3 — subtraction in parentheses, then multiply
  • 6*(21-1) — single digit times a parenthetical expression
  • 5*(7+15) — mixing single and double-digit numbers in parentheses

Examples: (12-2)/5, (3+9)*35, 47*(5-4)

Extreme (6 characters, no yellow hints)

Extreme mode shows only green (correct position) or gray (not in equation)—no yellow hints. This requires puzzles where logical deduction is possible.

We've added filters specifically for Extreme:

  • No swappable digits — If swapping two digits gives the same answer, the puzzle is excluded
  • No "any digit works" patterns — Equations like 23+4-4=23 where the repeated digit could be any number aren't fun without yellow hints
  • More distinctive operators — Puzzles include division or subtraction, which narrow down possibilities faster than addition or multiplication alone

Examples: 70/2+6, 18/2-6, 85*2-4

Same Game, More Puzzles

The rules haven't changed—same number of guesses, same hints system, same satisfying feeling when you crack it. You're just less likely to see the same puzzle twice.
