Six numbers. Four operations. One target.

Quadsix is a daily number puzzle. Combine the numbers you are given to reach the
target. Three fresh puzzles every morning, and everyone in the world gets the
same ones.

■ Learn it in 30 seconds

Tap two numbers, then tap + - × ÷. The two numbers merge into one.
Keep going until you hit the target at the top of the screen.

· Each number can be used only once
· Division must come out even
· Every intermediate result must be a positive whole number

Simple rules. But where you start changes everything.

■ Three puzzles, three difficulties

Easy, then medium, then hard.
Easy takes half a minute. Hard can take several.

Fewer steps means more stars. Nine stars a day is a Perfect Day.

■ A record that builds up

· Streak - keeps going as long as you clear the first puzzle
· Calendar - each day fills in by how well you did
· Archive - replay any past date, any time
· Stats - puzzles solved, best step counts, average time

Filling in the blank days is half the fun.

■ Made for you if

· You want a five-minute brain workout on the commute or before bed
· You like sudoku, math puzzles, or mental arithmetic games
· You enjoy staring at a hard problem until it cracks
· You want a playful way to practise arithmetic with your kids
