A standard underlying multi-outcome/multi-bet game is played, whereby a
bonus mechanism can reward the player relative to their underlying game
bets. Such a bonus may be triggered by a underlying game outcome (which
may or may not be an outcome which a bet can be placed) or by an event
independent of the underlying game. A bonus reward can be the playing of
one or more plays of the underlying game, optionally with different play
rules and/or pay schedules.
