Split #41 — the solution

The three rounds from November 9, 2026: twelve numbers each, split into four groups of three that add to the target — the one way each round allows, with its decoys and where the reasoning starts.

Round 1 — target 29

The numbers: 2, 14, 6, 16, 9, 20, 8, 13, 3, 1, 5, 19. 3 decoys.

The groups: 2 + 14 + 13, 6 + 20 + 3, 16 + 8 + 5, 9 + 1 + 19.

The decoys — triples that add to 29 but are not in the answer: 2 + 8 + 19; 14 + 6 + 9; 20 + 8 + 1.

Where to start: 16, 13, 3 and 5 sit in only one on-target triple, so their groups are certain — start there.

Round 2 — target 34

The numbers: 19, 20, 6, 15, 11, 10, 2, 4, 5, 12, 14, 18. 5 decoys.

The groups: 19 + 11 + 4, 20 + 2 + 12, 6 + 10 + 18, 15 + 5 + 14.

The decoys — triples that add to 34 but are not in the answer: 19 + 10 + 5; 20 + 10 + 4; 11 + 5 + 18; 2 + 14 + 18; 4 + 12 + 18.

Where to start: 6 and 15 sit in only one on-target triple, so their groups are certain — start there.

Round 3 — target 36

The numbers: 14, 10, 9, 15, 12, 18, 7, 13, 2, 19, 17, 8. 7 decoys.

The groups: 14 + 9 + 13, 10 + 18 + 8, 15 + 2 + 19, 12 + 7 + 17.

The decoys — triples that add to 36 but are not in the answer: 14 + 10 + 12; 14 + 15 + 7; 10 + 9 + 17; 10 + 7 + 19; 9 + 15 + 12; 9 + 19 + 8; 15 + 13 + 8.

Where to start: 18 and 2 sit in only one on-target triple, so their groups are certain — start there.
