Poker Hands by Jordy Thys

Introduction

MagiScript has a built-in database for several cards stack. Jordy Thys has contributed this code which can calculate poker hands and display the hands on a PeekSmith screen. The code is slightly updated to use the latest features of Atom / MagiScript.

The Routine

Have a spectator cut the deck until they are satisfied, let them choose how many poker hands they want to be dealt, and let them choose which pile they want.

The magician can name all five cards from the pile.

The magician can also name the cards from the other piles upon request.

The effect uses a memorized deck. You can set the stack in the MagiScript Editor’s Settings.

Four digits are entered into Atom:

First two digits: the stack value of the bottom card after cutting (peek at the bottom card)
Third digit: number of hands to deal
Fourth digit: the chosen hand

This effect is based on an idea by Craig Raley of the “TAP Users Group”.
