EveryMemoryNumber Sequence Game
2, 4, 8, ? - spot the rule and pick what comes next. A free number sequence game that trains pattern logic, with three lives and a rising difficulty. Play it right here.
⚡ Quick answer
A number sequence game shows a series of numbers following a hidden rule and asks for the next one. It trains inductive logic - spotting a pattern from examples and applying it. Our puzzles mix arithmetic, geometric, square-number, Fibonacci-style and growing-difference patterns. The fair score is your streak against your own previous best, not an IQ or age comparison.
Key takeaways
- Spot the hidden rule in a number series and pick the next number.
- Patterns include arithmetic, geometric, squares, Fibonacci and growing gaps.
- Trains inductive logic - inferring a rule from examples and testing it.
- Three lives; beat your own best streak, not an IQ or age chart.
Number sequence puzzles are a staple of brain games and reasoning tests: you're shown a few numbers - 2, 4, 6, 8 - and asked what comes next. The trick is reading the rule. Some grow by adding, some by multiplying, some by squaring, and some hide a sneakier pattern entirely.
Play the round above (find the rule, tap the next number), then read on for the rules you'll meet and how to read your score honestly.
How to play
You get three lives and the patterns get less obvious as your streak grows.
- Tap Start - a sequence appears with a '?' at the end.
- Work out the rule, then tap the correct next number from four options.
- Each correct answer adds to your score; a wrong one costs a life.
- Three wrong answers ends the game; your best score is saved on your device.

What it trains
Number sequences are a clean inductive-reasoning workout:
- Inductive logic - inferring a rule from a handful of examples.
- Numerical pattern-spotting - noticing differences, ratios and squares.
- Hypothesis-testing - checking a guessed rule against every term.
Like any single puzzle type, it mostly improves your speed at these puzzles - enjoyable practice, not a proven IQ boost.
The patterns you'll meet
Knowing the families helps you check fast:
- Arithmetic - add a constant: 3, 7, 11, 15, …
- Geometric - multiply: 2, 6, 18, 54, …
- Square numbers - 1, 4, 9, 16, …
- Fibonacci-style - each term is the sum of the two before it.
- Growing differences - gaps that increase each step.
The honest way to read your score
Compare your streak only to your own past runs. There's no population 'normal' to chase here, and a single run is noisy.
If you like reasoning puzzles, try sudoku and the magic square, and use the memory test online for a repeatable self-check.
⚠ When to talk to a professional
This is a non-medical logic game for fun and practice, not an IQ test or measure of brain health. Performance varies with practice and familiarity. If you're worried about a real, persistent change in your thinking, speak with a qualified healthcare professional rather than reading anything into a game score.
