Type the answer, watch it explode
Numbers, equations and BODMAS expressions fall; the instant what you have typed equals an answer on screen it fires. No Enter key, no hesitation.

NourForge Number Mayhem
Number Mayhem turns mental arithmetic into an arcade run. Answers fire the moment they match, every fifth level is a BODMAS level, five world sizes and four difficulties each keep their own Top 1000 table, and the Free edition is the complete game to Level 100.
PLAY IN YOUR BROWSER
The Free edition, no download.
Keyboard required; Chrome or Edge on a desktop computer.
CAPABILITIES
Designed for a clear, reliable workflow.
An arithmetic arcade game: type the answers to falling numbers, equations and BODMAS expressions before they reach the ground, and pop conga lines of digits.
Conga lines of digits
Trains of one digit ride down the field: tap the digit to pop the front member, or hold the key and let the game pop them in rhythm. From Level 51 some lines need two keys held.
A BODMAS level every fifth wave
Brackets first, then squares, division and multiplication, then addition and subtraction; each expression is worth 40 points and arrives on its own level.
Three maths levels
Level 1, 2 and 3 change only which operations appear and how early, and whether negative answers occur. Speed, damage and scoring are the same for everyone.
Five world sizes and four difficulties
Tiny (10 across) to Max (100 across); Easy to Extreme change only how health is regained. Every combination keeps its own Top 1000 table.
Original chiptune audio
Synthesised music and effects with independent music and effects volume.
LEARN
Why practise arithmetic in an arcade game?
Mental arithmetic is easy at a desk and hard under pressure. Number Mayhem rewards the next correct answer, not the fastest guess, and never stops the rain to wait for you.
