Quick Stats




Welcome Deals
When you first sign up, each site will show you a series of welcome deals. These are your main money-makers. Buy the ones that give you a large amount of bonus SC relative to the purchase price. They come in cascading waves -- completing one deal unlocks the next. Budget somewhere around $200-500 total across the welcome deals on a single site, as they keep showing you new offers after each purchase.
How to Play Through Your Balance
The best game for grinding through a large SC balance is Gravity Plinko. It has around a 95% return rate, low variance, and is easy to set on autopilot.
Here are the exact settings to use:
- Risk level: Low or Medium
- Bet size: as small as possible
- Balls per drop: 50
- Enable autoplay
With the minimum bet size, each set of 50 balls costs 10 SC. So if you have a large unplayed balance, you can set the number of autoplays to match and walk away.

Example: Playing Through a 400 SC Balance
This is an example of how to set up Gravity Plinko to grind through a 400 SC unplayed balance.
With minimum bet size, each set of 50 balls costs 10 SC. To cover a 400 SC balance, set autoplay to 40 rounds. Hit start and let it run. At 95% return, you can expect to end with around 380 SC -- giving you a clear path to redeem once the playthrough is complete.

The Promo Ban
One thing to be aware of with B2 sites is the "Promo Ban." If you see a message like the screenshot when you open the store, it means the site has flagged your account and will no longer show you exclusive welcome or reload deals -- only the standard flat packs.
Being promo-banned does not stop you from playing or redeeming. You can still withdraw your balance normally. It just means the site will not be as profitable going forward, and you are effectively reduced to collecting your daily bonus.

How to Avoid the Promo Ban
There may be some merit to pacing yourself. Instead of immediately buying all the welcome offers and grinding through your balance in one session, try mixing in other games and working through your balance more slowly. Redeeming in smaller amounts may also help fly under the radar. If you can delay the promo ban even by a few days, you may unlock additional deal waves which means more profit overall. It is not guaranteed, but worth considering if you want to maximize the return from each site.
