head to head
Neither is meaningfully harder - they pose close to the same test. The widest gap is variance, and it is a single point.

Optimization · Systems & Chaos
A solo poker roguelike about engineering scoring engines from a randomised shop.

Optimization · Systems & Chaos
A roguelike tower-defense hybrid about escorting a crystal through a randomised dungeon.
Balatro leans Optimization (Systems & Chaos); Dungeon of the Endless leans Optimization (Systems & Chaos).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Balatro
Drag-and-click cards; no mechanical demand at all.
Dungeon of the Endless
Pause-friendly control, no twitch demands
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Balatro
No opponent; blinds are fixed scripted targets.
Dungeon of the Endless
Monster waves spawn by fixed door-opening rules
Balatro leans a little harder on variance, though the gap is small.
Balatro
Shop offers and card draws gate every run.
Dungeon of the Endless
Unknown rooms and random hero or item finds
Balatro leans a little harder on optimization, though the gap is small.
Balatro
Joker synergies and scoring math are the core puzzle.
Dungeon of the Endless
Dust economy and turret placement are the real game
A matching score does not mean a matching test. Two games can both sit at 10 on execution and demand completely different things of you - which is why the reasoning above matters more than the number beside it.
