It is pre monthly bonus, not sure why Symphonized wrote it as Monthly time but I guess the monthly bonus will be coming soon.
Here is the link for the pre monthly bonus https://playstake.io/bonus?code=OctoberPreMonthly0610aH
Enjoy and have fun with it, hope you can turn it multiple times
Or you can claim it now then wait for the weekly bonus so you can have more balance to play in the weekend.
