Session Review

A gambling tracker that runs in your browser, not an app you install

Nobody remembers a losing session accurately. The bad nights compress into "I was unlucky" and the good ones expand into evidence of something. A log is the only thing that survives that, and it takes about twenty seconds per session. Everything on this site is arithmetic on numbers you typed, kept in your own browser.

You cannot review a session you did not record.

Add a session

Money in and money out are enough for most of this site. Bet size and spins are optional, and only those two unlock a realised RTP, because buy-in and cash-out cannot produce one. That is explained below.

Why two fields are optional

Money in and money out cannot give you an RTP

This is the mistake almost every session tracker makes. You put in RM200, you walk away with RM50, so it looks like you got 25% back. That number is not an RTP and it is not close to one.

RTP is returns divided by total stakes, and total stakes is not RM200. If you cycled that RM200 through a thousand RM1 spins, you staked RM1,000 and got RM850 back, which is an 85% realised return, not 25%. The same session produces wildly different numbers depending on which denominator you use, and only one of them is the RTP.

So this log asks for bet size and spin count separately. Enter them and it can compute a realised RTP that means something. Skip them and it will still give you net result, cost per hour, hit rate and streaks, and it will not pretend to give you an RTP it cannot derive.

How to log a session

Four fields, two of them optional

  1. Record the date and the game. The game name matters because RTP and volatility differ between titles, and a log that pools them is measuring the mixture rather than the game.
  2. Enter money in and money out. Buy-in and cash-out are the two figures you always know. Everything on the totals page that needs nothing else is derived from these.
  3. Add bet size and spin count if you have them. These two are optional and are the only route to a realised RTP. Without them the RTP field stays blank rather than being estimated from the buy-in.
  4. Add the minutes played. Minutes turn a net result into a cost per hour, which is the figure that compares one night to another when the buy-ins were different.

Nothing is sent anywhere. The entry is written to your browser's own storage the moment you press Add, and it is still there the next time you open the page on the same device.

Questions

Frequently asked

Why keep a gambling session log?

Because memory edits itself. Losing sessions compress into a general sense of bad luck and winning ones stay vivid, so an unrecorded history is systematically more flattering than the real one. A log takes about twenty seconds per session and replaces an impression with a number. It does not improve your odds and it is not supposed to.

Can I work out my RTP from what I put in and took out?

No. RTP is total returns divided by total stakes, and the amount you brought is not the amount you staked. A RM200 bankroll cycled through 1,000 spins at RM1 is RM1,000 of stakes. Using buy-in as the denominator produces a number that looks like an RTP, is far lower than any real one, and means nothing. That is why bet size and spin count are separate fields here.

Is any of this uploaded?

No. Sessions are stored with localStorage in your own browser. They are not sent to a server, nobody else can see them, and they do not sync to another device. Export the JSON if you want a copy, because clearing browser data will take the log with it.

How many sessions before my numbers mean anything?

More than most people expect, and the honest answer depends on how much your own results vary. The variance page computes a confidence interval from your own logged sessions rather than quoting a rule of thumb, and in almost every case the interval is wide enough that a run of ten or twenty sessions supports no conclusion at all.

Where the numbers you are logging come from

A log is only worth keeping if you have something to compare it against. Three of those comparisons live elsewhere.

The RTP your game is supposed to have

47 Pragmatic Play titles with the provider's published figure and a source link for each, spanning 95.45% to 97.02%. A realised RTP is measured against something, and this is the something.

What the session was expected to cost before you played it

The same arithmetic run forwards, from an RTP and a bet size to an expected cost per hour. Logging afterwards tells you what happened. This tells you what to have expected.

Whether your casino deployed that RTP at all

Providers ship one title at several RTP settings and the operator chooses which to run. The published figure is not always the figure you played, and there is a log there for recording what your own game screen shows.
