Free Slots Explained: How They Differ From Real Slots
How free slots work, whether their maths matches real-money slots, what bonus rounds do, and what the numbers look like in two real slot games.
On this page
A free slot is a slot machine game played with virtual coins. Its reels, symbols and bonuses can look identical to a real-money slot, but nothing you win can be withdrawn, and its return to player (RTP) is set by the publisher, not by a gambling regulator. This guide explains how the maths of a free slot works, using two real examples from Cashout Arcade, and what you should and should not read into a big win.
What counts as a free slot
Anything with reels, a pay table and a free-to-play currency. The category is wide: a three-symbol line game, a five-reel feature slot with a hold-and-spin bonus and everything between. What they share is that you can keep playing without paying, and that the coins have no cash value.
Is it the same maths as real slots?
Not necessarily. A free slot's RTP is whatever the publisher decides. A real-money slot in a regulated market may be bound by that market's rules and testing. So you cannot assume a free slot "plays like" the real one, and a free slot that feels generous may simply be tuned that way. The way to know is to read the published return, if there is one.
Cashout Arcade publishes it. Slots returns 97%; Sun Temple returns 96.998%, which is 97% rounded. Both are on the Odds page.
How a slot's pay table creates the return
The return is the sum, across all possible outcomes, of chance times payout. Here is Slots at the high-risk setting, using figures from the game:
| Result | Pays | Chance per spin |
|---|---|---|
| Three sevens | 2,964x | 0.0027% (about 1 in 37,000) |
| Three diamonds | 222.30x | 0.0216% |
| Three bars | 59.28x | 0.133% |
| Three bells | 14.82x | 0.583% |
| Three lemons | 7.41x | 2.2% |
| Three cherries | 4.44x | 3.93% |
| Two cherries anywhere | 1.48x | 22.89% |
Add up every chance times its multiplier and you get 0.97 of the bet per spin on average. The top prize, three sevens, contributes only a small share of that total. Most of the 97% comes from small, frequent wins like the two-cherry result, which is why a slot pays often but rarely pays much.
Compare the low-risk setting, where three sevens pay 182.29x but come up about 1 in 8,000 spins (0.0125%). The risk setting changes the shape of the results, not the 97%.
Bonus rounds and hold-and-spin, explained with Sun Temple
A feature slot adds bonus rounds. In Sun Temple, three or more Temple Door scatters start a bonus on about 1 spin in 107. The bonus is either Temple Link or Pharaoh's Offers, chosen at random, half each.
- Temple Link (hold and spin). The doors lock as golden scarabs and the empty cells respin three times. Each new scarab resets the respins. The bonus ends when the respins run out or all 15 cells are full. Scarabs carry values from 0.5118x up to the Grand at 1,023.7388x (0.2% of scarabs).
- Pharaoh's Offers. You are offered an amount, up to four times, and may take it or pass to see the next one; the last offer must be taken. Each offer is the previous one times 0.3x, 0.6x, 1x, 1.6x or 2.84x with set chances, which averages exactly 1x. So passing does not make the bonus worth more or less on average.
Line wins pay about 48.6% of the return and the two bonuses the rest, per the published figures. Across all results a spin wins something about 36% of the time (35.98%), and wins more than the bet about 10.5% of the time (10.46%).
Why a slot that "feels loose" may not be
Hold-and-spin bonuses arrive on a small share of spins and pay in lumps, so a short session either contains one and feels generous or does not and feels tight. Over thousands of spins the average settles near the published return; in a short run it does not.
What you win
Coins only. The biggest result in Sun Temple's table is 12,044x the bet, and the 50,000x per-round cap still applies, with a hard limit of 250,000,000 coins. These are caps, not targets.
Tips for playing safely
- Choose a session length before you begin.
- Treat big wins as luck, not skill; there is nothing to learn from them.
- Do not raise your bet to chase lost coins. The next spin does not owe you a win.
- Turn off or limit purchases if you notice you are buying coins impulsively; see How to Set App Spending Limits on iPhone.

Frequently asked questions
Do free slots pay out?
They pay out coins, never money. In Cashout Arcade coins cannot be withdrawn or exchanged for prizes.
Are free slots rigged?
Every result is random within the published odds and is decided on our servers. A game's published return (97% for Slots) is the long-run average, so single sessions can run well above or below it.
