Card Corner is a poker-inspired idle deckbuilder designed to sit in a small corner of your screen while you’re doing literally anything else, quietly ticking along until you glance back and realise you’ve become seriously invested in a run.
It’s out now on PC via Steam, published by Assemble Entertainment and developed by Conradical Games.
What it is
Card Corner mixes poker hands with idle progression, incremental upgrades, and deckbuilding. Cards are dealt, chips roll in over time, and you decide how hands, upgrades, and modifiers evolve as you go.
It’s built to support two types of play:
- Passive: Let it run, check in when you feel like it
- Active: Jump in to optimise your build and steer upgrades
The progression loop
This is where the “oh no” part gets you.
You level up, unlock deck mods and bonuses, stack permanent upgrades, and when you’re ready (or when the game humiliates you), you can reset a run to earn Ascendium for cross-ascension upgrades.
Steam lists 114 achievements, which is either a delight or a threat, depending on your personality.
The tiny window thing
The signature gimmick is that it runs in a small, resizable corner of your screen, and you can adjust size and position to fit your setup. It’s meant to be “always on, never in the way.”
