Casino games/Video poker

Video poker is a casino game found in many video games as a minigame used to gamble in-game currency. They will typically be identical to real-world examples; after all, video poker itself is a video game.

In video poker, RTP is typically very close to 100% with perfect play, with casinos relying less-than-perfect players to make their money. The decisions made in each hand can greatly affect the outcome, and as such strategy is an important part of the game.

Rules
Video poker is typically played with a single pack of (virtual) cards; any card that has appeared in the current hand, even if discarded, cannot appear again until the hand has finished.

The player is dealt five cards and can choose to discard any combination of cards in exchange for new cards. They then receive a payout depending on the composition of the final hand. The minimum scoring hand is a pair of Jacks, and as such the regular variant of video poker is known as "Jacks or Better".

Sometimes, the pack will include one or two jokers, acting as wildcards which can be treated as any other card in the pack (even those already present in the hand), known as "Joker's Wild". The minimum scoring hand usually becomes Two Pair when jokers are introduced, although sometimes Kings or Better returns the original stake.

More commonly, the 2s are instead treated as wildcards, known as "Deuces Wild". The minimum scoring hand becomes Three of a Kind in this instance.
