There are a thousand definitions and mine is just one among many, I’m aware. This is not a “right vs. wrong” matter, it’s how you cut things out.
For me, a roguelike has four rules:
- Permadeath—can’t reuse dead chars for new playthrus.
- Procedural generation—lots of the game get changed from one to another playthru.
- Turn-based—game time is split into turns, and there’s no RL time limit on how long each turn takes.
- Simple elements—each action, event, item, stat etc. is by itself simple. Complexity appears through their interaction.
People aware of other definitions (like the Berlin Interpretation) will notice my #4 is not “grid-based”. I think the grid is just a consequence of keeping individual elements simple, in this case movement.
Those rules are not random. They create gameplay where there are limits on how better your character can get; but you, as the player, are consistently getting better. Not by having better reflexes, not by dumb memorisation, but by understanding the game better, and thinking deeper on how its elements interact.
I personally don’t consider games missing any of those elements a “roguelike”. Like The Binding of Isaac; don’t get me wrong, it’s a great game (I love it); but since it’s missing #3 (combat is real-timed) and #4 (complex movement and attack patterns, not just for you but your enemies), it relies way more on your reflexes and senses than a roguelike would.
Some might be tempted to use the label “roguelite” for games having at least few of those features, but not all of them. Like… well, Isaac—it does feature permadeath and procedural generation, right? Frankly, I think the definition isn’t useful, and it’s bound to include things completely different from each other. It’s like saying carrots and limes are both “orange-like” (carrots due to colour, limes because they’re citrus); instead of letting those games shine as their own things, you’re dumping them into a “failed to be a roguelike” category.






Slay the Spire: yes. All four rules are there, specially in spirit. It’s also a deck-building game but that’s fine, a game can belong to 2+ genres at the same time.
I’m not sure on Balatro. I didn’t play it, so… maybe?
