A hand-drawn app about math skills with surprisingly few numerals. Daren Carstens of Carstens Studios wanted to show kids how genuinely fun and engaging math could be and so he designed this app. Users choose one of seven different puzzles, whether to play in a timed mode or not, they can choose the types of images or let the selection be random AND (and this is surprisingly rare in kids’ logic-related puzzle apps) they get to choose the level of difficulty they’d like to start at. Almost every other puzzle-type app on the market slowly builds the user’s skills by introducing new elements as the user progresses through the levels. This is excellent in theory, but in practice it can mean that if you’re feeling confident about your abilities and you want to jump ahead to the more challenging levels, there’s no way to do that without putting in the hours to play through the easier levels to “unlock” the more difficult ones. This self-determination of leveling is a feature that really sets this app above the rest because even if users try a level that’s too challenging, that just motivates them to back a little bit and see what they’ll need to learn to be able to solve the “too difficult” puzzle! The seven different puzzles themselves range in difficulty from relatively simple (pattern circles) to tricky to get the hang of (Category Stack was a bit challenging for me!). Some of the drawings are easier to differentiate than others (buttons of different shapes, colors and patterns are easy, complicated robots are a little harder), but since you can always opt to choose which drawings are used, you can always opt out of any that are frustrating to you. All-in-all, this is a beautiful app with very thoughtful design features and if you’re looking for an attractive way to get kids some math skills practice, this is an excellent choice.
