In more detail

The seven were chosen because they are among the most played in Britain and because their figures could be confirmed against two sources each. They cover the main kinds of slot: a low-volatility classic, two fishing games, two pays-anywhere grids, a book slot and a bingo-site favourite. Between them they show most of what a slot can do.
