What is quad nerdle?
Quad nerdle presents four nerdle grids on screen at the same time. Each grid has its own hidden 8-character equation, but you solve all four with a single shared set of nine guesses. Every guess you submit appears in all four 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. A new puzzle every day at midnight GMT.
Strategy
The key to quad nerdle is choosing guesses that give you useful information across all four boards at once. Early guesses should cover a wide spread of digits and operators. As grids lock in, you can focus your remaining guesses on the harder boards. Nine guesses sounds generous, but with four puzzles to solve you’ll need to be efficient.
If you’re familiar with Quordle (four Wordles at once), quad nerdle is the same concept but with equations instead of words.
The multi-grid family
If quad nerdle is too intense, try bi nerdle (two grids, seven guesses) or mini bi nerdle (two 6-character grids). If you want a single-grid challenge, classic nerdle or maxi nerdle (10 characters with brackets and powers) are great options.
