Try an explanation before choosing
Use an available hint at a move you cannot explain. Check whether you can describe the deduction afterward. In our course, work through a guided example and ask the same question. The two formats can complement each other: an app can help during a puzzle while a lesson gives you room to revisit the reasoning.
Understand what happens to notes
Brainium's support guide says changing note modes prompts a restart of the current puzzle. Review that prompt before changing modes midway through a game. More generally, decide whether you want to enter all candidates yourself or have assistance with the bookkeeping.
Check the current offer
Google Play labels Brainium's app as containing ads and in-app purchases. Our app page explains optional Pro alongside free browser and printable options. Check the purchase screen on your own device for the price and features; this comparison does not carry forward old fixed-price offers.
