Knowing when to cash out means evaluating Expected Value (EV). Unlike a fixed-reel slot, every fraction of a second updates the survival probability against the burst probability. The decision is continuous, not one-shot.
The expected value of holding the inflation for one additional increment (Δ) is:
E(Hold) = P(Survive) × (Current Multiplier + Δ) × Stake − (1 − P(Survive)) × Stake
- Break-even threshold: once the probability of a burst on the next increment exceeds Δ ÷ Current Multiplier, mathematical expectation turns negative (EV below zero). That is why "one more second" feels free and is not.
- House edge factor: SmartSoft's configuration implies a fixed 4.00% house edge, which is the flip side of 96% RTP. Over 1,000 simulated rounds at a constant 1.50x cash-out target, the theoretical return is:
Expected Return = Total Staked × 0.96
So 1,000 rounds at $1 CAD carry an expected long-run return near $960 CAD against $1,000 staked. A theoretical loss of roughly $40 CAD, spread unevenly across hot and cold streaks. Rarely does it arrive as a tidy $40.
A worked "uniform prior" analogy. Behavioural-science versions of the balloon task expose the same logic with simple arithmetic. Say a balloon withstands at most 20 pumps, and every threshold below that is equally likely. At 19 pumps, two outcomes remain, each with probability one half:
E(pump) = ½ × 0 + ½ × 20 = 10, against a guaranteed 19 for cashing out. Pumping is plainly worse.
Generalising: after i pumps, the chance of bursting on the next pump is 1 ÷ (21 − i), so the value of pumping is ((20 − i) ÷ (21 − i)) × (i + 1) versus an immediate payoff of i. Break-even lands near 10 pumps. The casino version differs in one decisive respect. The RNG applies a permanent negative margin, so unlike the lab task there is no setting where holding longer becomes EV-positive over time. Cash-out targets shape variance, not the house edge. Worth re-reading that sentence, because most "systems" sold online ignore it.
