Video Lottery Terminal Data

Description

Data on objects appearing in three windows on a video lottery terminal, together with the prize payout (usually 0). Observations were taken on two successive days in late 1994 at a hotel lounge north of Winnipeg, Manitoba. Each observation cost 25 cents (Canadian). The game played was ‘Double Diamond’.

Usage

vlt

Format

This data frame contains the following columns:

window1

object appearing in the first window.

window2

object appearing in the second window.

window3

object appearing in the third window.

prize

cash prize awarded (in Canadian dollars).

night

1, if observation was taken on day 1; 2, if observation was taken on day 2.

Details

At each play, each of three windows shows one of 7 possible objects. Apparently, the three windows are independent of each other, and the objects should appear with equal probability across the three windows. The objects are coded as follows: blank (0), single bar (1), double bar (2), triple bar (3), double diamond (5), cherries (6), and the numeral "7" (7).

Prizes (in quarters) are awarded according to the following scheme: 800 (5-5-5), 80 (7-7-7), 40 (3-3-3), 25 (2-2-2), 10 (1-1-1), 10 (6-6-6), 5 (2 "6"'s), 2 (1 "6") and 5 (any combination of "1", "2" and "3"). In addition, a "5" doubles any winning combination, e.g. (5-3-3) pays 80 and (5-3-5) pays 160.
