🃏 24 Game 🃏
The classic 24 card game! Given 4 random numbers, combine them using +, −, ×, ÷ to reach exactly 24. Every number must be used exactly once. Choose your difficulty (1–6, 1–9, or 1–13), build a streak, and beat your best time!
🔢 Sudoku 🔢
Classic 9×9 Sudoku with four difficulty levels — Easy, Medium, Hard, and Expert. Features a live timer, mistake counter, pencil notes, and 3 hints per puzzle. Beat your best time!
🧩 MathDoku 🧩
A KenKen-style arithmetic puzzle! Fill the grid with 1–N so every row and column contains each number exactly once. Each outlined cage must equal its target value using addition, subtraction, multiplication, or division. Choose from 4×4, 5×5, or 6×6 grids.
Angle Estimator Game
Train your eye for geometry! An angle is drawn on screen using two rays from a common vertex. Estimate the angle in degrees, then lock in your answer. The closer your guess, the higher your score — within 2° earns a perfect bullseye!
Fraction Frenzy
Compare or sort fractions in this fast-paced math challenge. Which fraction is bigger? Tap them in order smallest to largest — race the clock or survive on 3 lives!
Mean Median Mode Calculator
Calculate mean, median, and mode of any dataset with our free online statistical calculator. Get detailed step-by-step calculations, frequency tables, and comprehensive statistical analysis.
Triangle Calculator
Calculate triangle sides, angles, area, and perimeter using our advanced triangle calculator. Supports SSS, SAS, ASA, AAS, and SSA methods with step-by-step solutions and interactive visualization.
Guess the Equation
Inspired by Nerdle — guess the hidden math equation one character at a time in 6 tries. Every guess must be a valid equation (left side evaluates to the right side). 🟩 Green means the right character in the right place, 🟪 Purple means right character but wrong place, ⬛ Gray means not in the equation at all.
Guess the Formula
You're shown a table of x → y pairs — your job is to identify which of four formulas generated the data. Study the numbers, spot the pattern (linear, quadratic, exponential, modulo?), and select the correct formula before time runs out. On Medium and Hard difficulties you can also 'probe' additional x values to gather more evidence.
Math Flash Cards
Practice addition, subtraction, multiplication, and division with timed flash cards. Choose Easy, Medium, or Hard difficulty, track your streak, and sharpen your mental math skills in just 60 seconds!
Mental Math Challenge
A rapid-fire math game where you solve equations before a per-question countdown expires. Choose difficulty and operations, survive on 3 lives, and chase your personal high score — saved locally so you can always beat it.
Missing Number
Find the missing number in arithmetic sequences — 3, 4, __, 6. Tap one of four big colorful answer buttons. Race the clock in 60-second mode or survive on 3 lives. Easy, medium, and hard difficulty levels.
Number Bubble Pop
Colorful numbered bubbles float upward — tap them in ascending order (smallest to largest) before they escape off the top of the screen. Miss one and lose a life!
Number Chain
A math puzzle game inspired by word ladder: trace a path through a 4×4 number grid, chaining adjacent cells until their sum exactly matches the target. 10 levels, 3 lives, and a high score to chase — every chain is a new puzzle.
Number Tracing
Trace the shape of digits 0–9 with your finger or mouse. Follow numbered guide dots, draw over the faint digit outline, then check your accuracy. Free Practice and 10-digit Challenge modes.
Sequence Quiz
Spot the pattern and fill in the missing number! Each round shows a well-known mathematical sequence with the next term hidden. Identify whether it's Fibonacci, prime numbers, perfect squares, factorials, or one of nine other sequence types — then type your answer before the countdown runs out.
Shape Area Challenge
Put your geometry skills to the test! A shape is drawn on screen with labeled dimensions. Calculate the area using the right formula, then enter your answer before the countdown hits zero. Correct answers earn bonus points for speed.
Shape Sorter
Drag circles, squares, triangles, and rectangles into their matching outline slots in this fun shape-sorting game. Race the clock or sort shapes across 8 classic rounds — great for early geometry and shape recognition!
