What is octo nerdle?
Octo nerdle presents eight nerdle grids on screen at the same time. Each grid has its own hidden 8-character equation, but you solve all eight with a single shared set of 10 guesses. Every guess you submit appears in all eight grids simultaneously, with independent colour feedback on each:
- Green – correct character in the correct position.
- Purple – correct character, wrong position.
- Grey – character not in that grid’s solution.
Once you solve a grid it locks, so later guesses only apply to the remaining unsolved grids. With only 10 guesses for 8 puzzles, octo nerdle is the hardest of the multi-grid nerdle family – each guess has to give useful information about *all* the boards you haven’t solved yet. A new puzzle every day at midnight GMT.
Octo nerdle vs Octordle
If you’ve played Octordle – the eight-board version of Wordle – octo nerdle is the direct math equivalent. Same eight-board grid layout, same shared-guess mechanic, same satisfying click when a grid locks in. The difference: instead of finding eight hidden five-letter words, you’re finding eight hidden 8-character equations.
Octo nerdle is slightly harder than Octordle on the guess economy – you get 10 guesses for 8 boards versus Octordle’s 13 attempts. So you need to be even more efficient with each guess, and your opening moves matter more than in any other multi-grid game.
Strategy
With only 10 guesses for 8 boards, octo nerdle rewards methodical play more than any other multi-grid nerdle. Practical tips:
- Use your first two or three guesses to cover the widest possible spread of digits and operators. Don’t try to solve any single board yet – you’re collecting information.
- Track which characters are confirmed/ruled out per board. With 8 boards, a notes habit helps a lot.
- Once a board has 4-5 characters locked, you can usually solve it on the next guess. Keep that for when it’ll lock the most boards at once if possible.
- Don’t panic if you’re on guess 9 and still have 2-3 boards unsolved – a well-targeted guess often locks two or three boards at once if the remaining solutions share characters.
The multi-grid family
If octo nerdle is too intense, work your way up through the smaller multi-grid games:
- bi nerdle – 2 grids, 7 guesses (the math Dordle)
- mini bi nerdle – 2 mini grids, 6 guesses (gentler entry)
- quad nerdle – 4 grids, 9 guesses (the math Quordle)
- octo nerdle – 8 grids, 10 guesses (you are here – the math Octordle)
