Got this surprising email from RedFlush awhile back after RedFlush personal where unable to determine what slots I had played in a previous gaming session. Apparently the software provider MG did have a log of my gameplay.
There are 2 games that have tokens associated on them that you have played without completing the tokens, the games in question are Tomb Raider Secret of the Sword and Scrooge. The tokens that were initiated needs to be completed in full before wagering requirements on the specific games will be met. This means that until such time as you haven't completed these tokens, all future deposit will move to bonus amounts.
I've never heard of casino puting future deposits automatically into ones bonus account for playing these two games (and this wasn't in their T&Cs). However thats not the point. What really surprised me was that the software provider MG keeps tracks of my gameplay at RedFlush! Does MG keep tracks of every players gameplay at each casino that uses its slot games? I thought this was the casinos job? Why does MG care about which games I play?
This change in the bonus system has been around for a while, but no one from the casinos seems to have any idea, so players often don't get a proper explanation to problems with the bonus system. In addition, the system also produces "false positives" which result in WR not being reset even though the player has no incomplete games of this or any type.
The problem with games like TR II is that you can't simply play off a part collected set of tokens in order to zero out, you HAVE to deposit again and keep on playing with your own cash as bonus. This is not the case with Wealth Spa, as you can choose to play even one coin in the Smoothie bonus round.
An oddity is the Max Damage arcade game, which can show up as "part collected tokens" and "incomplete bet" if you have started a level, but not completed it. To reset this game I think you just have to sit there and get shot at until all lives have been lost and the level resets.
I have noticed that casinos will often dish out free spins on TRII, and this can lead to a situation where a player who does not normally play the game plays it as a "one off" because of the offer. This can cause them to have one or more passports sitting there for months, if not years, and on a game they don't play so they will not think that the free spins they were once given have caused the problem they are seeing now with WR carry over.
It seems that browser based casinos lock bonus balances out of these games, so when opened, players find they can only play them with the cash balance. The Viper download has no visible restriction, but the bonus tracking will register any collected tokens as an incomplete bet, and thus WR will not reset until it's fully completed from further deposits.
This description from MGS should be in the terms for the bonus system so that players who read it will know which games to check if they see that their WR has not zeroed on a fresh deposit.
It IS possible to "bust out" games like Scrooge and TR II by dropping the stake right down and playing to complete the tokens and play the bonus. This can even be done by cashing in some comps and then "busting" out the token collecting slots at the end of play on a bonus, and at least then if you bust out it will be done properly, meaning WR will not carry over on the next deposit.
As for the initial question, it should really be "why does the casino NOT know what slots I play?". The casino can get this information from their "back office", as Playcheck logs are available to them as well as to MGS. It's more likely that CS agents can't be arsed, so just say it can't be done (possibly because they think they will have to check every single game the player ever played over the life of their account).
It's been discussed before and some reps are more willing to elaborate than others.
