The users have the possibility to play up to 4 coins simultaneously, choosing for each one heads or tails. The order of the coins, starting from the top, is important to determine if the bet is winning or losing.&#x20;

\
For example, if my bet with 4 coins is **HTHH:**

* The result **HHTH** is a **losing** result.
* The result **HTHH** is a **winning** result.

By increasing the number of the coins the user can increase the amount of the prize in an exponential way. Said n the number of coins, the amount of the prize (P) is calculated in this way:

&#x20;                                                               $$P= 2^{n}$$

For this reason the possible plays are mainly 4:

* **Win 2 times\*** of the value of the pot with only one coin.
* **Win 4 times\*** the value of the pot with two coins.
* **Win 8 times\*** the value of the pot with three coins.
* **Win 16 times\*** the value of the pot with four coins.

The system already sets a minimum GWEI taking into account the actual GWEI of the blockchain in order to maximize the speed of the transaction and improve the user experience.\ <br>
