Today marks the final day of Club Nintendo's existence, making it your absolute last chance to cash in your coins for rewards.

Available rewards consist of more than 100 digital games for 3DS, Wii U, and Wii. These range from classic games like F-Zero, Ice Climber, and Super Mario World, up to much more modern games, like NES Remix, Kid Icarus: Uprising, and Super Mario 3D Land.

Any coins you have--which are earned by redeeming codes included with games/hardware, filling out surveys, and so on--must be spent before tonight at 11:59 PM PT. Unspent coins will be lost.

If this feels like yet another Club Nintendo deadline, that's because it isn't the first. March 31 marked the last day for earning coins, while April 30 was the last opportunity for claiming free gifts earned by reaching certain milestones. Today, however, truly marks the end of Club Nintendo, which will shut down for good tonight.

Nintendo announced its plans to shutter Club Nintendo back in January. The service will be replaced by a new rewards program, the details of which are still a mystery. We do, however, know it will cover 3DS, Wii U, smart devices, PCs, and Nintendo's next system, NX.
