An educational simulation, not gambling
Royal Dice Casino uses virtual chips only. There are no deposits, no withdrawals, no prizes and no real-money betting of any kind. It exists to show how games of chance work, using your own results.
One round in four steps
You need a phone (or computer) and two ordinary dice. The app keeps the books; the dice decide.
-
Set up
Choose a currency, a starting bankroll of virtual chips, how many rounds you plan to play, and a betting strategy.
-
Place your bet
Your strategy sets the stake. Tap Place bet and the chips leave your bankroll.
-
Roll real dice
Roll two physical dice and tap the face each one shows. No random numbers from the phone: the dice are yours.
-
Get paid by the board
The total of the two dice decides your payout from the board below. Then the next round begins.
Some totals pay five times your stake
The board never changes. Every round, your stake is multiplied by the number under your dice total.

Multipliers are the total amount returned, including your stake. A ₹100 bet that lands on 12 returns ₹500 (₹400 net profit). A ₹100 bet that lands on 7 returns ₹20 (₹80 net loss).
Choose how you bet
Start with one strategy and switch between rounds if you like. Every change is recorded in your recap.
Fixed
The same stake every round: your starting bankroll divided by the rounds you plan to play.
Martingale
Double the stake after every losing round and go back to the start after a profit. A classic system.
Percentage
Bet a fixed share of whatever your bankroll is right now, recalculated before every round.
Manual
Choose every stake yourself with quick chips, an exact amount, or one tap to repeat your last bet.
Built for honest reflection
No flashing lights, no "keep playing" nudges. Just your bets, your dice and your numbers.
A full session recap
A bankroll chart, every bet in a sortable table, your best and worst rounds, and reflection questions.
Your results to keep
Download a PDF report, a CSV history for spreadsheets, or a session file to share with a facilitator.
