It has nothing to do with spongebob or Squidward, It's just another game where you take house edge for free without involving any risk yourself.

25 BTC is huge amount of money, hope he makes It back =/

I'm not a game fan , I would personally would gamble It and try making at least $20 from It then I would hold or think how could I invest them and make even more. But if you decide to gamble you should minimally know what you are doing.
