Number Rules: Math Puzzle Quiz

Number Rules packs eight distinct math puzzles into one brain game and number quiz.
Train your mental math, logic, and focus across eight modes — formula, deduction, sequence, combination, Hidden, Spot-the-Lie, and Neon, plus the new Matchstick. 1,700+ stages you can play offline, with no wifi or internet needed.


🔥 Matchstick (NEW)
Move a single matchstick to fix a wrong equation.
Turn ＝ into −, or × into ÷ — one well-placed stick reveals the answer. 250 stages with two-digit and negative numbers sharpen your eye and your arithmetic.


🕵️ Spot the Lie
Four shape statements — three are true, one is a lie. Find the false one.
Each shape hides a number, so test the equations and tap the odd clue out. Property, comparison, and "B is lying" twists keep every deduction fresh. 150 stages.


✨ Neon
Build numbers from glowing 7-segment pieces, then assemble a formula.
Rotate, flip, and merge the segments to shape each digit, line them up with + − × ÷, and reach the target number. A hands-on, brand-new number-building puzzle. 250 stages.


🔍 Rule Discovery
Find the hidden math rule between two numbers — a deduction quiz that rewards logic.
Use step-by-step hints to narrow it down, then feel that satisfying "aha!" moment.
