I've been playing Challengers a ton on BGA. There is a lot more to it than it may seem at first and it's a very fun game.

Yesterday I was mentioning Azul as an example of a game that's very easy to teach and a lot of fun when played casually but at the same has great depth at high level play. I think Challengers falls into this space too. The award is well deserved IMO.

The Decision Space podcast has just covered the game if you'd like some more in-depth discussion. They rated it very high too.

Edit: I totally missed that Sea Salt & Paper got a recommendation too! It's one of my absolute favorite small deck games, very addictive! And I'd highly recommend Next Station: London too if you enjoy flip & writes. It has quickly become one of our comfort games.
