Roulette Wheel for FTBL Standard Game

Before the start of the match, the sectors on the roulette wheel are arranged in 4 colours — black and red (active sectors), blue and green (passive sectors). The distribution of colours in the active sectors is determined by the correlation of the ratings of the teams taking part in the match; the virtual weather conditions are determined by the total number of passive sectors on the roulette wheel.

Before the roulette wheel is rearranged into colours, the Game System selects at random three numbers which replace numbers 1, 1 and 22 blue – these are the away team’s goalkeepers (the home team’s goalkeepers – green 1, 1 and 22 – are on the roulette wheel from the start). The three displaced numbers are visualised in the form of three cards placed on the roulette wheel in the “Game Field” lobby.

Significance of the sectors on the roulette wheel in determining footballing events:

- black sector (active) – the home team has scored a goal.

- red sector (active) – the away team has scored a goal.

- green sector (passive) – the away team has attacked, but has not scored – the home team has cleared its lines

- blue sector (passive) – the home team has attacked, but has not scored – the away team has cleared its lines

- yellow sector – “Captain”.

The distribution of the coloured sectors is subject to the following rules:

- the number of blue + green sectors is determined by the virtual weather conditions and can vary between 6 and 30

- the number of blue sectors = the number of green sectors

- the correlation (number of red sectors) / (number of black sectors) = (home team’s rating*1.05)/(away team’s rating), i.e. the home team receives an extra 5% towards its rating

The number and location of sectors of various colours is fixed for each match and remains unchanged throughout the match, except when the ball lands in the “Captain” sector. In this event an extra mini-time is played. The result of this extra mini-time is either a goal for the home team or a goal for the away team. At this time all the sectors of the roulette wheel turn to red and black. The number of red and black sectors during an extra mini-time depends on the correlation between the separate parts of the teams’ current ratings. If there are no separate parts in the teams’ ratings, the whole “Captain” sector belongs to the team with the higher rating, and that team scores a goal; the extra mini-time is not played.

The extra mini-time is necessary in order to take into account as fairly as possible the effect of the teams’ current ratings on the outcome of the match.

The number of red and black sectors during an extra mini-time (when the ball lands in the “Captain” sector) is determined as follows:

N1 = MAX ([{N * R1 / (R1 + R2)}*36], 1)

N2 = MAX ([{N * R2 / (R1 + R2)}*36], 1)

Where

N1 is the number of sectors of the first team (black, home team)

N2 is the number of sectors of the second team (red, away team)

N is the number of active sectors during the match (36 is the number of passive sectors)

R1 is the current rating of the first team

R2 is the current rating of the second team

{…} is a fraction of a number

[…] is a whole number

MAX(…, …)is the maximum of two numbers.

If N1+N2 < 36, the rest of the field is changed to the colour of the team with the higher current rating.

Virtual weather conditions, which determine the number of passive (green and blue) sectors in each match, are selected at random.

In any match there can be between 6 and 30 passive sectors on the roulette wheel. They are always of an even number – they are divided equally between the teams. There can therefore be 13 different amounts of passive sectors.

The number has to be equal over a whole championship. If the number of matches in a championship is not divisible by 13, the remaining matches will be played at 6 and 30. If the remainder is an odd number, there will be one more match at 6 than at 30.

The number of passive sectors is decided at random before the start of a match, taking into account the numbers that have already been used.
