and displaying, in response to receiving the request for replay of the particular instance of the plurality of instances of the sub game, the particular instance of the plurality of instances of the sub game. ### Claim 5 (depends on 1) The gaming device of claim 1, wherein: the sub game data and the sub game metadata include sufficient information to provide a replay of the instance of the sub game. ### Claim 6 (depends on 1) The gaming device of claim 1, wherein the base game metadata include one or more of RNG data, starting credits data, credits wagered data, credits won data, ending credits data, slot symbol data or other game outcome presentation data. ### Claim 7 (depends on 1) The gaming device of claim 1, wherein the game round index marker comprises a render state field indicating that a game instance should render to a display. ### Claim 8 (depends on 1) The gaming device of claim 1, wherein the sub game trace is the same as the base game trace. ### Claim 9 One or more non-transitory media having software stored thereon, the software including instructions for controlling one or more devices to perform a method of recording gambling game events for replay, the method comprising: receiving, via a user interface, user input corresponding to a request for play of a gambling game; determining, via a control system comprising at least one processor, whether the gambling game is a base game or a sub game; in response to determining that the gambling game is a base game: controlling, via the control system, the display system to provide a sequence of images corresponding to an instance of the base game; determining, via the control system, base game data and base game metadata corresponding to the instance of the base game; and adding, via the control system, a base game trace to a game history data structure corresponding to the base game data and the base game metadata; in response to determining that the gambling game is a sub game: controlling, via the control system, the display system to provide a plurality of instances of the sub game wherein each instance of the sub game includes controlling the display system to provide a sequence of images corresponding to an instance of the sub game; determining, via the control system, for each instance of the sub game, sub game data and sub game metadata corresponding to each instance of the sub game; adding, via the control system, for each instance of the sub game, a sub game trace to the game history data structure corresponding to the sub game data and the sub game metadata;
