When Slingo Deal or No Deal loads, you’ll find yourself staring at a standard 5x5 grid, each containing a number, only here those numbers have been printed onto the banker’s famous red boxes. There’s a glowing green button to the bottom right of the screen that reads Start Game, and you should probably hit that button in a moment, but first you ought to set your bet level. After all, there’s a big difference between wagering £1 and £100 per game.
