# Boost Win Rate

                                            ![](https://263845718-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FykfxUEIWjqOyl5p8U4Ac%2Fuploads%2FzTmat7KAByYoIoYiOokm%2Fdownload-slap-kings-mod-apk%20\(1\).jpg?alt=media\&token=740844e8-cf81-40a3-82ee-92d317788bfe)                                              

By giving SPN to your SLAP, you have the possibility to improve its power and therefore its win rate.

You can do this 3 times per SLAP.

5% more win rate each time, for a maximum of 15% in total.

The cost in SPN varies depending on the rarity of the SLAP being fed:

Common: $20 in SPN

Rare: $30 in SPN

Epic: $40 in SPN

Legendary: $50 in SPN

On top of that, 0.05 BNB is added as fee (see  for more information)

And 50% of these fees will be used to buyback SPN and fulfil the contract that handles fights rewards.

All SPN used for the Boost Winrate are BURNED.
