Achievements
Spellington App contains a progressive achievements system which tracks progress on correctly spelled words, earned stars, perfect games, grades progress, and some hidden surprises.
So far, there are 25 achievements. Some of them are very challenging, but they are balanced to obtain a bunch of these in the early stages of the game.
The idea behind these achievements is to keep children engaged to the app by measuring progress, but also by offering a downloadable pdf containing a printable diploma the children can keep as a trophy.
Thanks for reading.
