Test your Brain: Tricky Puzzles is a lateral-thinking game in the Brain Test mould: each level poses a small problem, and the solution is almost never what the screen appears to be asking for.
You might have to drag one object onto another, tilt your phone, or use something from the question text itself. The whole genre works by teaching you to distrust the framing.
Lateral-thinking riddles where the intended solution deliberately isn't the obvious one — you often have to interact with the interface itself rather than answer the question as posed.
Most levels offer a hint, best saved for a puzzle you've genuinely exhausted.
Yes — tap and drag. Nothing to install.
