Size Variants: Micro to Maxi#
The core deduction loop stays familiar — guess the equation using green, purple, and black feedback — while the board width changes the puzzle space:
A five-character board, such as 8-5=3. Try it when you want a shorter equation or are learning how the colored clues work.
A six-character board, such as 15-7=8. It offers another place to practice equation structure before trying Classic.
Mini Nerdle SolverThe bridge between Mini and Classic. Its 7-character calculations add room for more structure without jumping straight to the full 8-character board.
The original daily game. This is the format behind NerdleBuddy's 17,723-form model, solver, strategy guide, and puzzles.
The long-form challenge. The wider board also introduces extra symbols such as brackets and squared/cubed operators, so order of operations really bites.
Gameplay Variants#
These change the format, pace, or way you play:
Speed Nerdle
Classic rules against the clock. You're given a starting guess, and hesitation costs you — time penalties punish slow or invalid entries.
Instant Nerdle
One guess, no warm-up. The game supplies starting clues and you deduce the completed calculation before submitting your only attempt.
Pro Nerdle
The sandbox: build your own Nerdle with extra math symbols and share it as a challenge link for friends to solve.
Instant’s current rules are described on the official Instant Nerdle page.
Multi-Grid & Puzzle Variants#
Bi, Quad & Octo Nerdle
Solve two, four, or eight grids with shared guesses. The lineup also includes Mini Bi for a shorter two-grid challenge.
Cross Nerdle & 2D Nerdle
Grid-based calculation puzzles that extend the equation idea across rows and columns rather than a single horizontal board.
Shuffle, Targets & Nanagrams
Other puzzles in the wider Nerdleverse, from rearranging tiles to building calculations that hit target numbers.
The Nerdleverse itself is one branch of a much larger family tree. For the geography, music, movie, and word branches, browse our complete list of Wordle spinoffs.
Which Variant Should You Play?#
- Brand new to Nerdle? Learn the rules with our how-to-play guide, then warm up on Mini before moving to Classic.
- Playing with kids? Micro and Mini keep the arithmetic friendly while teaching the deduction loop. Teachers: we wrote a whole classroom guide.
- Chasing lower guess counts on Classic? That’s our specialty — the strategy guide covers data-backed openers, and the solver ranks the next guesses from your feedback.
- Short on time? Instant gives you one attempt, Micro uses the shortest board, and Speed adds a timer. Choose the format you enjoy; one attempt does not necessarily mean a quick solve.
- Want unlimited practice? Many official modes are daily, while the official site also offers archive and custom formats. On NerdleBuddy, replay any date from our archive or grab a random puzzle with hints, any time.
Frequently Asked Questions#
How many Nerdle games are there?
The official site currently offers more than 20 free math and number games. The lineup includes daily puzzles, size variants, multi-grid challenges, archives, and custom or replayable formats, so '20+ games' does not mean every game is a separate daily puzzle.
What is Mini Nerdle?
Mini Nerdle is the 6-character version of Nerdle. The rules are identical to Classic — guess the equation in 6 tries with green, purple, and black feedback — but shorter equations make it noticeably easier.
How do you play Mini Nerdle?
Exactly like Classic, just smaller: guess a 6-character equation (think 5+8=13, the little sibling of 52-34=18) in six tries, reading the same green, purple, and black feedback. With fewer slots there's usually room for only one operator, so pinning the equals sign early does most of the work. It's the friendliest on-ramp before graduating to the 8-character Classic.
What is the hardest Nerdle variant?
Among the equation-length variants, Maxi is designed as the largest challenge: its 10-character calculations can include brackets and squared or cubed operators. Difficulty across different game formats is subjective, so there is no single objectively hardest Nerdle game.
What is the difference between Nerdle and Maxi Nerdle?
Size and toolbox. Classic hides an 8-character equation using + - * / with six guesses. Maxi stretches the board to 10 characters and adds brackets and squared/cubed operators, so expressions like (3+4)*6=42 come into play. Same feedback colors, same six guesses — just more slots to reason about and more ways an expression can be built.
What is Instant Nerdle?
Instant Nerdle gives you one attempt and supplies clues on the board. You deduce the completed calculation before submitting that attempt.
Can you play more than one Nerdle per day?
Yes. You can play several official games, use supported archive, replay, or custom formats, and practice unlimited original puzzles with hints on NerdleBuddy. Availability varies by game rather than every variant following one daily-only format.
What math game is like Sudoku?
If Sudoku's pure logic is your thing, try KenKen and Kakuro, which add arithmetic to the grid. Nerdle scratches a related itch from the other direction: instead of filling a grid, you deduce one hidden equation from color feedback — closer to a numeric detective story than a placement puzzle. Six guesses, school-level arithmetic, and the same 'one more round' pull.
