Been using HARD Penny Dell Logic Problems for a couple months now. It’s basically a collection of brain-teasing logic puzzles you can play on your phone. Pretty solid app if you’re into that sort of thing.
Here’s what you do: there are tons of different logic problems to solve. You gotta use your deductive reasoning skills to figure out the answers. It’s got a nice clean interface with an undo feature so you can mess around without worrying about making mistakes. And the auto-solve option is handy when you get really stuck.
Look, if you’re into logic puzzles and brain teasers, you’ll probably like this. It’s not perfect – the ads can be kinda annoying if you don’t pay – but overall it does the job. Worth checking out if you want to give your mind a workout.
