Split #44 — the solution

The three rounds from November 12, 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 34

The numbers: 1, 9, 19, 11, 2, 16, 7, 20, 18, 17, 13, 3. 3 decoys.

The groups: 1 + 16 + 17, 9 + 7 + 18, 19 + 2 + 13, 11 + 20 + 3.

The decoys — triples that add to 34 but are not in the answer: 1 + 20 + 13; 11 + 16 + 7; 18 + 13 + 3.

Where to start: 9, 19, 2 and 17 sit in only one on-target triple, so their groups are certain — start there.

Round 2 — target 28

The numbers: 17, 12, 14, 2, 1, 19, 8, 5, 11, 16, 4, 3. 4 decoys.

The groups: 17 + 8 + 3, 12 + 14 + 2, 1 + 11 + 16, 19 + 5 + 4.

The decoys — triples that add to 28 but are not in the answer: 12 + 5 + 11; 14 + 11 + 3; 1 + 19 + 8; 8 + 16 + 4.

Where to start: 17 and 2 sit in only one on-target triple, so their groups are certain — start there.

Round 3 — target 24

The numbers: 7, 15, 3, 9, 11, 8, 19, 10, 1, 5, 6, 2. 6 decoys.

The groups: 7 + 11 + 6, 15 + 8 + 1, 3 + 19 + 2, 9 + 10 + 5.

The decoys — triples that add to 24 but are not in the answer: 7 + 15 + 2; 7 + 9 + 8; 15 + 3 + 6; 3 + 11 + 10; 11 + 8 + 5; 8 + 10 + 6.

Where to start: 19 and 1 sit in only one on-target triple, so their groups are certain — start there.
