Two games, one brain workout
Deduction first, arithmetic second — the puzzles you see on social feeds, gathered into a proper collection.

- Ten categories take you from Starter to Grand Master
- 100 hand-crafted levels, ten per category
- Grows from 2 symbols and simple sums to 5 symbols, order of operations and negative answers
2, 5, 10, 17 — what comes next?
A sequence runs, and one value is missing. Find the hidden rule behind each series.
- Easy, Medium and Difficult tiers keep the pressure on as you improve
- Rules range from plain addition to multi-step logic
- Pure sequence reasoning — no calculator, no guessing
