The doubling run

$5 to a millionaire

The rules

  • It is the same rock paper scissors deal — one hand, two players, locked in.
  • Win and your money doubles. Move on to the next opponent with everything still on the table.
  • Nothing is taken while you keep going. The 3.7% fee is charged once, on your profit only, at the moment you take it.
  • One loss ends the run. From $5.00 it takes 18 straight wins to pass a million.

How the run works

You play the ordinary rock paper scissors deal. Beat your opponent and the whole amount rolls into the next deal against a new opponent — you never have to stop to carry on. Take the money whenever you like: that is the only moment the fee is taken, and only from your profit.
