Just in case you are not familiar with Splinterlands, let me tell you about what is SPS. Splintershards (SPS) is the official governance token for Splinterlands. This token is determine you power for voting in the development proposal of the game. With higher staked SPS, you can have more power that affect the result. So, it's like you are having the the game with staked SPS.
Beside the voting power, there are many benefit you can get from having the SPS :

• Reward Multipliers from SPS Staking.
  This probably the most important points for staking the SPS for those who are focus on play to earn. This game have it's rewards calculation, and one of the variable is the staked SPS. With more SPS, you can have more rewards multipplier which will give you more SPS rewards as you win the game !

• Earn sps and voucher.

Splinterlands is offering earning for those who stake the SPS in form of SPS itself and voucher that you can use for discount or simply sell it on the market. Extra revenue! Not only that, you can rent your staked SPS for other, and earn DEC as rewards based on the price you put on the market ! Another way to earn with SPS~

• As a tournament requirement
  Now this is another part for the gameplay. If you are unaware, rewards from the tournament is very very good compared to what we need to pay for the entry. If you are confidence with your skill, then you need to try join the tournament for good rewards ! But each tournament have it's own sps staked requirement based on the league cap, with higher league can required higher SPS staked but having higher rewards as well.

SPS Gives Rewards on Another Games !

Now you might be surprise, can SPS really give you rewards on another games ? Well, the answer is yes ! I just knew it after jump into the #arcadecolony ecosystem. There, SPS staker can earn rewards in form of colony (on moonkarts games) and GLX (on Genesis League Goals).

This could expand the usage of SPS !
Not just having the earning from Splinterlands, you can also earn more from the other games, so there would be even higher APR !
