- Users tried to drag the entire stack of chips instead of one 10-point chip at a time. We assumed people would drag them one at a time because they had to bet on multiple criteria and didn't allow for stack-dragging.
Decision-Making process too lengthy
- Many users felt that there were too many criteria selection and criteria betting rounds. This made the decision-making process too long.
- Users had to perform some mental math to figure out how to distribute their 100 chips within and across criteria.
Safety
Certain combination of criteria have no restaurant choices
- One group of users decided on Indian food in Chinatown. There were no restaurant choices for these final criteria.
- Users bet quickly on criteria choices and didn't realize there was no chips left in the bank. They assumed their bets were saved, and the app did not provide feedback on this misconception.
Insufficient feedback for user manipulation
- The app did not inform users that their choices were not saved when they used up all their chips. One user kept betting chips and assumed his choices were being saved.
Too many rounds
