What Makes These Puzzles Different

Unlike typical number puzzles that rely primarily on arithmetic, Six-Figure Logic combines simple math with logic-based clues.

Clues may involve:

1. Arithmetic relationships (+, −, ×)
2. Comparisons (<, >)
3. Number properties (even, odd, prime, not prime)
4. Positional relationships (adjacent, between, not between, closer to)
5. Relative size (is/not largest, is/not smallest)
6. Exclusive Or “XOR” (A or B is even but not both)
7. Global constraints (e.g., no two values sum or multiply to a given number)

Every clue matters. There are no redundant or “useless” clues. Each one contributes meaningfully to the solution.

Progressive Difficulty

1. Easy (50 puzzles)
2. Medium (50 puzzles)
3. Hard (50 puzzles)
4. Expert (50 puzzles)
5. Super-Six (25 puzzles)

A smooth progression helps build confidence, pattern recognition, and advanced reasoning skills.
