TON Bingo! Instant Draw - what's that?

We're getting pretty close to publishing our Web-App (actually, it's coming any day now), so it's time we revealed the idea.
The application is formed around smart contract-enabled instant lotteries based on TON jettons.
The word "instant" here means that each time you decide to participate, you get the result either the moment you send the transaction or within a couple of minutes after it's completed, depending on the mechanics of the game you choose.

The first game you'll find is called Piggy Bank. Some of you might know how this works already - except no you don't 😄
In Piggy, every transaction has a 1-10% chance to win - you actually pick it yourself.
The bet size is calculated automatically depending on the current size of the pool and the chosen chance to win. The bigger the pool is at the moment and the bigger the chance you choose - the bigger should be your bet.
Upon winning, the user receives 75% of the pool. 15% is left to form the starting pool for the next Piggy (which starts immediately after the previous one breaks), and the remaining 10% goes to cover the commission and gas.
All this brings the ROI to fascinating 90%!

If you played a Piggy before, you're quite familiar with the part above.
What you're not familiar with is - there are two kinds of Piggies: the Ordinary one and the DEX-Buy Piggy.
This is a feature we're really proud of. Not only Instant Draw is a fun and fair game for users, it's also a very useful tool for TON jettons that helps them grow in value.
We'll explain the mechanics in the next post.

Stay tuned. Stay Bingo!

P.S. On the screenshot you see the first three jettons you'll be able to win in the Piggy.
Congrats to DmitriyShilo for being the first one to guess!
