Editor for player behaviour and design

Katrin writes about the side that is not in the paytable: documented design effects, common errors and limits set before the start.

3 articles on this blog
Basis: published research
Not a substitute for counselling

Her topics are near misses, losses dressed up as wins, the missing time cue in the interface, and how all of it acts on the length of a session.

Her basis is published research and the text of regulation; there are no observations of individual players.

What her texts do not contain: remote diagnoses, case stories, or advice meant to replace counselling.

„The strongest limit is the one drawn before the start." – Katrin Sommer
