The third box on the «Basics» tab changes with the kind you chose: on stamps it is «stamps per reward», on points it is «points per riyal». (Web)
In the Aloke Owners app, open «Loyalty programme» from the home screen, then «Programme basics». (iPhone and iPad, Android)«Programme basics»: the switch, and how customers collect.
Type the number in the box directly under the kind.How many stamps a reward costs (or how many riyals make a point).
Press «Save» and read the number back once the page returns. That is the one that will actually apply.
Stamps per reward
How many stamps a customer needs. From 2 to 50, default 6, meaning the sixth is on you. Anything outside the range is clamped to the nearest limit, so read the number back after saving.
Points per riyal
How many points a customer earns per riyal on the bill. From 0.1 to 10; 1 is the usual answer.
