Humble Choice (formerly Humble Monthly) is the subscription service from Humble Bundle where each month they give you a fresh set of a games to redeem.
The amount of games you get to keep depends on what tier you pay for. Their Lite plan gives you access to the Humble Trove, which is quite a decent selection of DRM-free games you can access any time and 10% off in the Humble Store.
The higher Basic plan also has the Humble Trove access, 10% off in the store and you can also redeem three games from their monthly list. The top end is the Premium plan which gives you 20% off in their store, Humble Trove access and expands the games you can redeem to 9 (although they often have a deal on new subscriptions to claim all 12 games).
Here's what they have this month (first three in bold have Linux native builds):
- Nimbatus - The Space Drone Constructor
- Deadly Days
- ADOM (Ancient Domains Of Mystery)
- Yakuza 3 Remastered
- The Surge 2
- DIRT 5
- Paradise Killer
- Kill It With Fire
- Bee Simulator
- S.W.I.N.E. HD Remaster
