Fifty free spins at NZ$0.20 look like NZ$10 of play, and on paper they return about NZ$9.60. After the casino applies a 40x wagering requirement to the winnings, the simulated average cash-out falls to about NZ$5.50, and most players walk away with nothing.

The spins return about NZ$9.60 on average; after wagering the average cash-out is about NZ$5.50.

Step one: the paper value

Free spins are bets the casino pays for. Fifty spins at NZ$0.20 is NZ$10 of stakes; at a 96% return the expected winnings are 50 × 0.20 × 0.96 = NZ$9.60. The median player wins less (NZ$7.80) because a few large wins carry the average; the best tenth of players win NZ$14.40 or more.

Step two: the wagering on the winnings

Winnings from free spins usually arrive as bonus money with wagering attached. At 40x, NZ$9.60 must be bet NZ$384 before it can be withdrawn. At a 4% house edge the expected cost of that betting is NZ$15.36, larger than the winnings themselves, so the first-order estimate of the cash-out is zero.

Step three: what players actually did

The simulation plays each player’s winnings through the wagering at NZ$0.20 a spin and stops at zero. The average cash-out was NZ$5.48, but only 8.9% of players ended with any money at all; the median was NZ$0. The average exceeds the formula because a balance cannot fall below zero, so the occasional large win is kept in full.

How these numbers were made. The simulations use a model pokie, not a real game: 96% return to player, medium volatility, a fixed bet on every spin, 20,000 simulated players per case. It shows how wagering behaves; it does not tell you what a particular pokie will do.

What to look for in the terms

  • Wagering on winnings: 0x (“no wagering”) is worth far more than 40x. Spins with no wagering are rare, so check the page.
  • Win cap: a NZ$50 cap on free-spin winnings limits the lucky tail that makes the average.
  • Spin value: NZ$0.10 or NZ$0.20 per spin changes the value fivefold at the same count.
  • Game: the spins are fixed to one pokie, so the RTP and volatility of that title are what you get.

Questions readers ask

Are free spins worth taking?

If they come with no deposit and low wagering, yes: the cost to you is zero and the expected return is above zero. If they come with a large wagering requirement, expect a small average value and a most-likely result of nothing.

Why is the average above the formula?

The formula treats losses as unlimited; a real balance stops at zero. That floors the bad outcomes and keeps the good ones, which lifts the average.
