The setlist
Do maths people ask you to do again.
A magician can name the day of the week you were born on — in their head, in a second. These are real number tricks (place value and clock-style “mod” maths), not gimmicks. Learn the secret, then perform. The unit of progress here isn’t a streak — it’s a show you gave someone.
Opener Any-Day A fresh date every day — guess the weekday, then learn the Doomsday method that gets it every time. The show Show Mode Hand someone your phone. They enter a birthday or hide a digit; you take a bow. Nothing is saved or sent.
The secrets Three real tricks ×11 by adding the middle · squares ending in 5 in one step · casting-out-nines to find a missing digit. Every step is honest maths.
Rehearse, then perform
The tricks are self-working — the maths does the magic — but a smooth performer has done the mental adding a hundred times. Drill the arithmetic at MentalForge, then come back here and put on a show.
Honest promise: this makes practice fun and gives you something to show off — it isn’t a claim to make you a genius. On-device, no account, no timer, no streak, nothing leaves your phone.
