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

Reads · Mind & Math
A simultaneous-turn tactics game where you plot moves against a human's unseen plan and watch both resolve.

Reads · Mind & Math
A bluffing-heavy card game where reading your opponent across three rounds outweighs raw card power.
Frozen Synapse leans Reads (Mind & Math); Gwent: The Witcher Card Game leans Reads (Mind & Math).
Gwent: The Witcher Card Game leans a little harder on execution, though the gap is small.
Frozen Synapse
Simultaneous turns remove all dexterity
Gwent: The Witcher Card Game
No timing involved; purely strategic card placement
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Frozen Synapse
You must predict a human's hidden plan each turn
Gwent: The Witcher Card Game
Two-out-of-three rounds create meta-game bluffing and baiting
Gwent: The Witcher Card Game leans a little harder on variance, though the gap is small.
Frozen Synapse
Hidden enemy orders and fog on some modes
Gwent: The Witcher Card Game
Card draws and hidden hand matter but deck is known
Gwent: The Witcher Card Game leans a little harder on optimization, though the gap is small.

Line-of-sight geometry and timing are calculable
