There are 3 phases to playing Deal or No Deal: The Big Draw:
Phase 1: Buying tickets and boosting the prizes
You must buy a ticket to play Deal or No Deal: The Big Draw. Ticket prices range from £0.10 minimum bet to £100 max bet. Once you buy your ticket, you'll see the 16 prizes that will be locked away in silver cases. You have the option to boost the size of one or more of the cases. Choose your boost price between £0.01 and £100 per boost. Then, click on a prize you want to boost, and five closed cases will appear on your screen. Open a case, and it will reveal the prize boost. You can continue boosting prizes until the timer reaches 0 and the game starts.
Phase 2: The first 20 balls
The 16 prizes are placed in randomly numbered cases. The live host will start the bingo ball machine, sending out 20 balls. Any case with a matching number to the bingo ball will be eliminated from the game. You need to eliminate at least 7 seven cases to qualify for the Banker's offer. If you didn't reach the 7 case limit, the dealer will offer to sell you an additional 6 balls. The price depends on the prizes remaining in the cases. If you remove 8 or more cases, a multiplier ranging from 2x – 25x will be applied to your cases.
Phase 3: Banker Offer
If you qualify for the Banker offer, you will receive the option to accept the cash offer, refuse the deal, and continue trying to remove more cases, increase your multiplier, or switch cases. If you switch cases, select one of the remaining cases on the board and open it to discover if you made a good deal.
