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

Execution · Practiced Mastery
Anxiety-fueled block-climbing puzzler wrapped in a relationship-drama narrative.

Execution · Practiced Mastery
A Tetris variant testing placement speed with a square-building scoring layer.
Catherine leans Execution (Practiced Mastery); The New Tetris leans Execution (Practiced Mastery).
The New Tetris leans a little harder on execution, though the gap is small.
Catherine
Climbing block towers fast under time pressure
The New Tetris
Fast precise placement under speed is the lead axis
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Catherine
Versus mode exists but is niche
The New Tetris
Multiplayer adds light prediction, mostly solo speed
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Catherine
Some randomized block layouts on replays
The New Tetris
Piece bag is random but bounded and mappable
Catherine leans a little harder on optimization, though the gap is small.
Catherine
Block-technique vocabulary solves each tower
The New Tetris
Building 4x4 squares for bonus rewards deeper strategy
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.
