A gaming machine is a device (whether wholly or partly mechanically or electronically operated ) that is designed so that:
(a) it may be used for the purposes of playing a game of chance, or a mixed game of chance and skill; and
(b) it may be operated wholly or partly by:
(i) inserting a token, coin or banknote into the device; or
(ii) electronically transferring credits or tokens to the device; or
(iii) using credits or tokens in the device (whether those credits or tokens are held, stored or accredited by the device or elsewhere); and
(c) because of making a bet on the device, winnings or other rewards may become payable.
