Field notes
The listed game path moves from array lookup and three sorting methods into stacks, queues, searching, trees, graphs, and harder topics such as memory hierarchy. The free tier is described as including the first five games and a daily set of questions; monthly or yearly Pro removes ads and daily limits. The page says progress stays on the device.
