Tafelmonsters! is an app for iOS I created for Malmberg when working for IJsfontein Interactive. The objective was to create an app that would facilitate memorising multiplication tables. The game was created in a month by myself together with Tim Groeneboom (programmer).
In Tafelmonsters! Players have to feed a candy to an approaching monster. The monster is hungry for a candy that has the solution to the multiplication sum that he is calling for. Players can drag or swipe to throw the candy with the solution after they selected the solution from the number bar above the candy. For this App, I came up with the concept, UI and game-design. I also monitored a play-test which helped us to create the user-interface inserting the right answers on the candy.
During the play-test, I found out kids don’t have any knowledge of a conventional input interface like a calculator. Therefore, some kids insert 7 and then 1 when they want to enter 17 since the dutch pronunciation is ‘seven-teen’. To allow kids to handle the input that way, we enabled them to insert singles first and decimals later OR vice versa.
The app was released in 2012, although it is still prominently used to this date. It also was also selected ‘Best Educational App’ by Volkskrant (Dutch newspaper) and eduapp.nl.
You can download it from the iOS App Store.
