OK Win NotesOK Win Loss Calculator: What a Session Costs
Type a stake, a number of rounds and a game’s chance, payout and fee, and the calculator shows the average cost of the session and how little luck can undo once rounds add up. It opens on one hour of colour bets at ₹100 a round.
Before any number goes into the boxes above, ask where it came from. A sum is only as good as its source.
Where did your figure come from?
| The figure | Where it sits | Use it? |
|---|---|---|
| Chance, payout and fee | The game’s own rules, wherever your screen states them, on a page at an address you can account for | Yes. Choose My own numbers in the Start from list, type them in and read the cost first |
| A percentage labelled RTP | On the tiles of the OK.Win page, as the page’s own display | Only as an average. A later section shows what it leaves out |
| “This game returns 98” | A chat, a video or a group | No. Score the address it came from in the link checker before you weigh it |
| Nothing at all | A tile that shows no numbers | Then the price cannot be worked out, and this tool has nothing to add |
At the time of writing (8 October 2026) the category row on OK Win’s page held eight labels with no counts, and each tile we could see carried an RTP percentage. We cannot check any of them, quote none and call no game fair. The games guide walks the lobby.
The starting hour
The preset is a colour bet in a ten-outcome round, an illustration: five digits of ten pay (four at 2×, one at 1.5×), with a 2% fee taken from each stake. Stake ₹100, 60 rounds in the hour.
| Reading | Value |
|---|---|
| What the game keeps | 6.9%, or ₹6.90 of every ₹100 |
| Staked in all | ₹6,000 |
| Expected loss | ₹414 |
| Typical swing | ± ₹729 |
| Hour ends ahead | 28% |
The swing is bigger than the cost, which is why plenty of single hours end ahead. Stake changes the money and not the odds: the same hour at ₹10 a round costs about ₹41, at ₹500 about ₹2,070, and 28 in 100 end ahead at both.
Luck fades as rounds add up
Same colour bet at ₹100 a round, 60 rounds an hour:
| Time played | Rounds | Staked | Average cost | Typical swing | Ends ahead |
|---|---|---|---|---|---|
| 1 hour | 60 | ₹6,000 | ₹414 | ± ₹729 | 28% |
| 3 hours | 180 | ₹18,000 | ₹1,242 | ± ₹1,263 | 16% |
| 7 hours | 420 | ₹42,000 | ₹2,898 | ± ₹1,929 | 7% |
| 10 hours | 600 | ₹60,000 | ₹4,140 | ± ₹2,306 | 4% |
| 30 hours | 1,800 | ₹1,80,000 | ₹12,420 | ± ₹3,993 | ≈ 0% |
The cost grows in step with the rounds. The swing grows only with their square root, so 30 times the rounds multiplies the cost by 30 and the swing by about 5.5. Around the third hour the two are level. By the thirtieth the cost is a little over three times the swing, and luck no longer rescues the session.
A percentage on a tile gives an average, not a shape
RTP, short for return to player, is the share of stakes a game hands back on average over a very large number of plays. Take an invented game that hands back ₹95 of each ₹100. It could be built three ways, each at ₹100 a round for 60 rounds with no fee:
| Built as | Cost | Typical swing | Ends ahead |
|---|---|---|---|
| 47.5 wins in 100, paying 2× | ₹300 | ± ₹774 | 30% |
| 25 wins in 100, paying 3.8× | ₹300 | ± ₹1,275 | 43% |
| 10 wins in 100, paying 9.5× | ₹300 | ± ₹2,208 | 39% |
All three keep ₹5 per ₹100, so the cost is the same. The swing and the chance of ending ahead differ, and the last column is not the price. A label alone fixes the first number and leaves the other two open.
Using your own figures
Copy the chance of a win as a count out of 100, what a win pays (with your stake counted inside it) and any fee. Choose My own numbers in the Start from list, type them in with your stake and the hours, then read the cost, then the swing, then the chance of ending ahead. For a tile that shows only a label, type half the label as the chance, 2 as the payout and 0 as the fee.
What this calculator cannot do
We are not OK Win and read no game’s rules. We cannot say what any tile’s chance, payout or fee is, and the tables here are sums on invented games. For a Wingo-style round with every bet side by side, use the Wingo calculator. The lottery guide prices a three-dice round, and the tools index lists the rest.

Common questions
Why does the tool show an average cost when my hour might end ahead?
The average is where the sums settle over many sessions, and one hour is a single draw from them. On the starting setup, 28 hours in 100 end ahead, yet the average hour still costs ₹414. Both are true at once, because the hours that end ahead are outweighed by the rest.
What does the typical swing in rupees tell me?
It is the usual distance a session can stray from the average result, up or down. On the starting setup it is ± ₹729 around a cost of ₹414. It is not a limit, so a bad session can cost more than the average plus the swing.
Does a bigger stake change my chance of finishing ahead?
No. At ₹10, ₹100 and ₹500 a round, the starting hour ends ahead 28 times in 100. The cost scales with the stake, at about ₹41 for the first and ₹2,070 for the last. A bigger stake makes every sum of money bigger and leaves every chance where it was.
How many rounds are in my hour?
Divide 3,600 seconds by the length of one round: a 60-second round gives 60 rounds an hour and a 30-second round gives 120. We read no OK Win round length, so type the one your screen shows. The Wingo calculator compares round lengths for one bet.
Can I type an RTP label in as the house edge?
Almost. A label of 95 would mean ₹5 of each ₹100 is kept, so the edge is 100 minus the label. The calculator has no box for it, so choose My own numbers in the Start from list and type half the label as the chance, 2 as the payout and 0 as the fee. The cost comes out right, but the shape of the game is a guess.
Why does the last row show ≈ 0% and not 0%?
The ≈ marks a figure the tool estimates instead of counting exactly, which it does for very long sessions. At 1,800 rounds the estimate is smaller than 1 in 1,000, so ≈ 0% means very small and not impossible.
