Every number on the board belongs to exactly one set, and every set sums to the same target. Benchmark deals 24 numbers: 4 pairs, 4 triplets, and the Final 4. Advanced deals 25 with a Final 5 and targets up to 999.
You crunch in rounds: find the 4 pairs first, then the 4 triplets, then the final group. Tap numbers to select them — when your selection reaches the round's size, it checks itself. A wrong set flashes and clears; a right one bursts and vanishes. Clear all nine and the board is crunched.
Hints (5 per game) reveal one number of a valid set for the current round. Revealed numbers lock in but score nothing.
Every number YOU select in a correct set scores its face value. The maximum is the target times nine — find every set with no hints and the board pays in full. Hinted numbers never score, and revealing the Masterpiece costs the target value for each unsolved set. Wrong attempts cost nothing but show in your stats.
A perfect score with no hints earns Flawless Masterpiece. Under 90 seconds: Lightning Solver. No hints: Pure Logic Genius. All nine sets: Skilled Strategist.
Finish and you receive a Real World IQ score: your score performance (0–100, with a small penalty per wrong attempt) multiplied by 2.0, plus a speed bonus of up to 20 for beating par. The maximum is 220.
The largest numbers on the board can only live in pairs — a 92 against a target of 99 needs exactly a 7. Start every game by pairing off the giants; the pairs round often solves itself from the top down.
Target ends in 4? A pair's last digits must sum to 4 or 14. Scan by units digit before adding anything in full — it eliminates most of the board in seconds.
After the pairs fall, everything left belongs to triplets and the final group. The smallest numbers on the board are almost always final-group material — they need the most partners to reach the target.
Pairs are findable and the final group solves itself by elimination — the triplets round is where the search space peaks. If you spend a hint, spend it there.
When 8 sets are gone, the last four (or five) numbers ARE the final group — but check the arithmetic anyway. Confirming it lands the full set value into your score.
