About Prism Post
Step inside Prism Post, a bright optical postal bureau with four offline casino games and a hands-on way to understand the rules.
POSTAL ROUTES SLOTS
Play ten fixed routes with original postal symbols. Choose a Routing Lens path before a spin to double that route for one extra line unit. Inspect your result receipt to see which leftmost matching symbols paid and how each award was calculated.
THREE CARD AND DICE TABLES
Play Pass Line Craps with a visible point and roll history. Try eight-deck Baccarat Punto Banco with Player, Banker and Tie bets, hand totals and drawing-rule explanations. At Casino War, decide whether to surrender or add a War stake when the opening ranks tie.
ROUTE STUDY
Work through twelve interactive prediction exercises across the four rooms. Get an explanation for every answer, revisit a lesson and save mastery marks. Study uses no Chips and changes no game probabilities.
LOCAL PROGRESS
Your free-Chip wallet, recent result journal, study marks and sound preferences stay on your device. Pause and return to an ongoing round. No login, advertisements, Chip purchases or online game service. A free refill is available when your idle balance is below the refill threshold.
Prism Post contains simulated casino play for an adult audience. Virtual currency has no real-world value. No real-money gambling, cash prizes, purchases, exchanges or withdrawals.
