The future of Google’s game streaming service, Stadia, is pretty uncertain. Things right now don’t look particularly great, considering the overall muted launch of the service and its less than stellar performance so far. Whether Google can pull this one up is anyone’s guess, but in the meantime, there are free games for the taking, and April’s offering is quite the mix of different experiences.

For April, those subscribing to Stadia Pro can get three games for free. First is The Serious Sam Collection, which collects all the mainline series for the beloved shooter franchise. Second is Stacks On Stacks (On Stacks) which is a puzzle game focused on, you guessed it, stacking. Lastly is the arcade throwback, Spitlings, that allows you to edit your own levels for co-op fun.

All three titles will be free on Stadia Pro starting April 1st (and that’s no joke). The current free titles are Metro Exodus and Thumper, so don’t forget to redeem those before March ends.
