# Gem Sockets

<figure><img src="/files/lPpjGnQelFz4zSbltwiS" alt=""><figcaption></figcaption></figure>

Every Vehicle NFT has four Gem Sockets in which you can mount a Gem.

Gem Sockets can have one of four colors: red, green, yellow, or blue, and the color of each Socket is randomly determined when a Vehicle is created. Vehicles can have multiple Sockets with the same color.

The Sockets are initially locked and cannot be equipped with Gems, but each time the Vehicle reaches a certain level, one gets unlocked and available to mount a Gem. For more details about level-up process, refer to the [\[Level page\]](/perplay-whitepaper/game-fi/nft/level.md).

Each Socket can only be mounted with a Gem of color that matches the color of the Socket.

<table><thead><tr><th width="168">Socket Color</th><th>Effect When Mounted</th></tr></thead><tbody><tr><td><mark style="color:red;">Red</mark></td><td>Vehicle’s Base Speed increases by N%.</td></tr><tr><td><mark style="color:green;">Green</mark></td><td>Vehicle’s Base Luck increases by N%.</td></tr><tr><td><mark style="color:yellow;">Yellow</mark></td><td>Vehicle’s Base Energy increases by N%.</td></tr><tr><td><mark style="color:blue;">Blue</mark></td><td>Vehicle’s Base Durability increases by N%.</td></tr></tbody></table>

Vehicles have a Plus Mark which can be used as a special Gem Socket of rainbow color in addition to the four basic Gem Sockets. It is opened at the initial state, and a Rainbow Gem Socket can be freely mounted with a Gem of any color. The Gem in the Rainbow Socket will have a twice effect value than the original one.&#x20;
