Sumrex hints — 2026-05-01
A spoiler-safe walkthrough for Sumrex #12 (2026-05-01). Each hint reveals a single deductive step; the full six-cell answer is tucked behind a toggle at the bottom.
Hint 1 — how big can a single digit get?
Reveal hint
Your six rexes must sum to exactly 12. Even if every other row plays its smallest available digit, any single rex can be at most 6. So any cell with a digit greater than 6 can be crossed out straight away.
Hint 2 — your first rex
Reveal hint
Scan the columns once the early crossings are down. Column 5 ends up with only one candidate row — row 1. That cell must be a rex.
Hint 3 — one step from done
Reveal hint
By this stage you should have 4 rexes down, with their digits totalling 7. That leaves a budget of 5 across your final 2 rows. Only one arrangement of your remaining candidates sums to exactly 5 — those must be your last rexes.
Show today's answer
(R1C5=3) (R2C1=2) (R3C4=1) (R4C2=1) (R5C6=3) (R6C3=2) — the six digits sum to 12.
