Do you trust your instincts?
Rules are simple:
Based on the revealed card, guess whether the next card would have higher or lower rank!
If you don't feel confident in guessing the rank, you may alternatively guess the suit colour.
While guessing the next card might be simple, it could potentially be helpful to you other games such as Poker & Blackjack.
Additional setting such as number of decks and rank orders can be applied to custom your needs.
* This game does not promote any elements of gambling; instead as a tool to test intuition with mathematical support (probabilities).
