Cross Current

What it is

Cross Current is a standalone puzzle from Sixth Sigil, a fantasy card battler by Eric Crook, and it opens right in the browser. You get a twelve-card deck and three lanes, and on the final turn you have to work out which card goes first and which comes next. The official site says it is free, needs no download or account, and works with mouse or touch. The site states that the project's graphics and narrative text are AI-generated and its code is AI-assisted; it doesn't name the models. What sets it apart is that the whole thing is a single turn, so you can practise card sequencing without playing a full match.

Who it's for: card-battle players who enjoy thinking through play order.
