Free Rewards
The Sponsored Video Rewards system is a feature that allows players to earn in-game rewards by watching advertisements. This system was introduced to the game between patches 7.11 and 7.12.
This system can be accessed through a button labeled "Earn Free Rewards" above the news section on the right of the main menu. If you do not see this button you are either not currently eligible or have already viewed the daily allotted ads.
The requirements for having access to the Free Rewards feature are not fully known. Players from North American, South American, European, and Asian regions have reported being able to access Free Rewards, however living in these regions does not guarantee a player access.
Functionality
On the Free Rewards menu, the player can click a button to watch a sponsored advertisement.
The player has a limited amount of ads that can be watched per day. The exact amount is unknown and seems to vary per person; it can sometimes be as little as 2 ads, but can also as much as 30 ads per day. These ads can auto-play for about 6-10 ads, after which the player will have to manually continue watching ads.
The progress bar goes up to 50. Once completed, the bar will stay at 50 until another ad is watched, then it will reset and start counting again at 1. Thus, players are granted another opportunity to progress the track and earn more rewards. If it is the player's first time watching ads, the progress bar will start at 49 out of 50.
If the Free Rewards button is not visible on the main menu, either the daily ad limit has been met or the player is not currently eligible to watch ads.
Rewards
With each advertisement watched, the player earns 
10 or more coins, and the watch count progress bar moves up.
The player will be granted a Reward Chest for every 10 ads watched. Every 50th ad watched will grant a Grand Chest.
Any of the following types of Store items can be earned from these chests:
While it's not currently known which specific items can be earned from the chests, higher values rewards like Skins can only be obtained from the Grand Chest.
