Add, subtract, multiply, divide — calculate before the clock runs out.
A question comes up with four answers under it. Tap the right one before the clock runs out. The whole screen turns the color of the player whose turn it is, so nobody has to ask.
THREE WAYS TO PLAY
• Pass and play — answer all your questions, then pass the phone.
• Duel — face to face across one phone, both on the same question at once. A wrong tap sits you out.
• Solo — just you, against your own best run. Beat it for a new best.
FIVE MODES
Add, Subtract, Multiply and Divide — or Mixed, where any of the four can come up and you won't know which.
HOW HARD
• Easy, Medium or Hard — 12, 10 or 8 seconds a question, with bigger numbers each step up.
• Adaptive — get it right and the numbers grow; miss and they shrink. Each player picks up just below where they finished last time.
HOW IT ENDS
• A set number of questions — 10, 15 or 20 each. Most right answers wins.
• Beat the clock — from 30 seconds to 2 minutes each. Fit in as many as you can.
• Race to a score — first to 10, 15 or 20 points. Fewest questions to get there wins.
A tie goes to whoever was faster.
