How the Bankers Offer is calculated

  Unlike the banker in Deal or no Deal, the offer on this website, doesn't take into account the players personality. Some details of how the offer is calculated are shown below:

  1. The Average: All calculations start from the board average, that is the total value of the remaining boxes divided by the number of remaining boxes.

  2. The Round: the initial calculated offer is made after selecting 5 boxes and then further offers after 3 more boxes.

    This websites 'banker' calculates a rough offer based on round number. Other factors like the power 5, red/blue balance, bankers penalty, the spread & rounding are then used to adjust this.

    • Round 1 - remaining boxes 17 - rough offer = 31.25%
    • Round 2 - remaining boxes 14 - rough offer = 33.33%
    • Round 3 - remaining boxes 11 - rough offer = 34.48%
    • Round 4 - remaining boxes 8   - rough offer = 38.46%
    • Round 5 - remaining boxes 5   - rough offer = 38.46%
    • Round 6 - remaining boxes 2   - rough offer = 35.71%
  3. Bankers Penalty: When the calculated offer falls by 50% or more (from the previous round), the banker will make a penalty offer in that round and further reduce the calculated offer by at least 40%. The greater the fall the greater the penalty. Applies on rounds 2 to 5.

    Few players accept this offer from the banker, but it encourages players to give greater consideration to later offers.

  4. Red/Blue Balance: The ratio of reds to blues, will boost the offer if reds out number the blues and reduce it if blues out number reds. The greater the imbalance the more the adjustment.

  5. Power 5: Individual numbers are given a 'weighting', positive for reds and negative for blues. £250,000 the most positive & 1p the most negative.

    The sum can be a negative or a positive number, negative values reduce the offer and positives increase it. This includes the top and bottom 10 but after the top/bottom 5 it becomes a minor effect.

  6. The Spread: The banker gives improved offers from round 4 where the remaining box values are close together. The is a weak effect at round 4, moderate at round 5 and strong at round 6. So for example at round 6 when two close values are the last remaining boxes you get greatly improved offers that are close to the average.

    Other factors apart from the average are ignored when this factor comes into play.

  7. Rounding: Above certain break points rounding takes place to the nearest, 1,000, 500, 100, ...
