Brain Test 3 is a puzzle game built around a story. You play Alyx, who is searching for six power gems to save her dying father, and the puzzles are the obstacles along the way. Characters from earlier games in the Brain Test series appear as you go.
It suits people who like logic puzzles and riddles but want them tied to a plot that runs for a long time. The developer describes it as free to download and free to play, and as playable without an internet connection.
The build we hold is Brain Test 3: Tricky Quests 1.82.3 (APKS split bundle) for Android 7.0 and up.

Objects you pick up go into an inventory, and you use them on puzzles in the scene. The inventory also lets you merge two objects into a new item, which is how some of the obstacles get past.
The puzzles include reverse logic problems and riddles that need you to read clues closely. Puzzle types are mixed through the story rather than grouped in a separate mode.
Alyx meets dozens of characters, and several of them only help once you have chosen the right reply. The chat is set up as a role playing exchange, so the choices carry through the conversation rather than ending it.
Getting a reply wrong can send you down a different path, so the conversations test social judgement as well as the puzzle-solving.
Alyx's workshop is a base you build and expand over the course of the game. Its idle resource generators keep producing resources while you are away from the puzzles, and those resources go toward the tools and machines you add.
Costumes, pets and workshop improvements are offered as customization, so you can change how Alyx looks and what surrounds her as you progress.
A hint system is included for the more complex riddles, so a stuck puzzle does not have to be abandoned. The developer lists it as a replacement for the older help options.
The game runs offline with no internet connection needed, and the developer says it can be played with one hand. It is listed as free to download and free to play.
