Split #27 — the solution

The three rounds from October 26, 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 30

The numbers: 16, 2, 12, 18, 14, 13, 8, 1, 5, 7, 4, 20. 3 decoys.

The groups: 16 + 13 + 1, 2 + 8 + 20, 12 + 14 + 4, 18 + 5 + 7.

The decoys — triples that add to 30 but are not in the answer: 16 + 2 + 12; 12 + 13 + 5; 18 + 8 + 4.

Where to start: 14, 1, 7 and 20 sit in only one on-target triple, so their groups are certain — start there.

Round 2 — target 36

The numbers: 16, 3, 1, 20, 15, 6, 12, 19, 11, 18, 14, 9. 5 decoys.

The groups: 16 + 11 + 9, 3 + 19 + 14, 1 + 20 + 15, 6 + 12 + 18.

The decoys — triples that add to 36 but are not in the answer: 16 + 1 + 19; 16 + 6 + 14; 3 + 15 + 18; 15 + 12 + 9; 6 + 19 + 11.

Where to start: 20 sits in only one on-target triple, so its group is certain — start there.

Round 3 — target 32

The numbers: 18, 5, 9, 17, 2, 14, 10, 13, 11, 6, 8, 15. 7 decoys.

The groups: 18 + 5 + 9, 17 + 2 + 13, 14 + 10 + 8, 11 + 6 + 15.

The decoys — triples that add to 32 but are not in the answer: 18 + 6 + 8; 5 + 17 + 10; 5 + 14 + 13; 9 + 17 + 6; 9 + 10 + 13; 9 + 8 + 15; 13 + 11 + 8.

Where to start: 2 sits in only one on-target triple, so its group is certain — start there.
