A coin-operated entertainment machine such as a fruit machine is operated by a player to produce a displayed combination of symbols. When a winning combination is obtained a mechanism (10) is operated to give an appropriate payout, although first the player may be given the opportunity of changing the pay-out by operation of a gamble device (16). An adjustment mechanism (18) is also provided and this can operate in correspondence with the gamble device to change the displayed symbol combination to accord with the changed pay-out value. Hold buttons (14) may be provided for holding the displayed symbols during a subsequent game.
