Bankroll Simulator
See how your balance would move over N spins. Simulated with realistic hit frequencies and payout distributions. Run it multiple times — each session is different.
What This Simulator Shows
The chart plots your cumulative profit/loss over the number of spins you chose. The line shows how your balance would move if you played at the given bet size on a slot with the given RTP and volatility. Each run is different because the random number generator produces a unique sequence every time — just like real slot sessions.
Run it 5-10 times at the same settings. Some sessions end green, some end red. That's variance. The spread between your best and worst sessions tells you how much volatility actually affects your bankroll. High-volatility simulations swing wildly — you might see +$500 one run and -$400 the next. Low-volatility sessions cluster closer to the expected return.
The model uses synthetic hit frequencies calibrated to match real slot behavior: low-vol games hit ~30% of spins with small payouts, high-vol games hit ~16% of spins with larger payouts plus rare big hits. Payouts are scaled to match the RTP you enter. It's not an exact replica of any specific slot, but it captures the mathematical shape of how different volatility profiles feel.
