Numberle · strategies
Digits, not words.
With only 10 possible symbols per slot (vs 26 for Wordle), Numberle is faster to narrow — but duplicates are common and tricky.
Cover the range
Your first guess should use 5 different digits spanning the full 0-9 range. A guess like 13579 or 20486 immediately classifies half the digit pool.
Duplicates are legal
Unlike some number puzzles, the target CAN repeat digits (e.g. 33147). If you get a yellow for 3, it might appear more than once — test for doubles early once you have a hit.
Positional lock-in
A green digit is fixed — build around it. Shift yellows to untried positions. With 5 slots and 10 symbols, two greens usually leave very few valid numbers.
In 1v1
Speed matters. Memorize a fixed opener (e.g. always start with 13579) so you never spend time on guess 1 — your real thinking starts at guess 2.
