Deal Or No Deal Instant Win is not a slot game but you can use your free £5 from Sky Vegas to play on it.
Chose a box and watch carefully, as boxes are eliminated. After each round the banker will make you an offer. Collect if you think its fair or carry on going. Its just like the real game but the main difference is that the real game is free to play. You just have to apply and get accepted. In the online game, you have to place a bet and this determines the value of the boxes.
