Gardenscapes asks you to build and decorate, while Brain Test asks you to doubt every obvious answer. It is a trivia and riddle game from Unico Studio, released on November 20, 2019, and it is free to play on Android 7.0 or newer. Google Play shows over 100 million installs and a 4.7 rating from about 10.1 million ratings.

First steps after install: no account, no connection needed

Brain Test is distributed through Google Play, so the install is a normal store download under the package name com.unicostudio.braintest. The size depends on your device, since the version label varies by phone. Check that you run Android 7.0 or later before you start.

Once it opens, you can play without an internet connection. The description stresses offline play several times, which suits flights, commutes and dead zones. The content rating is Everyone, so the game can be handed to most of the household.

The puzzles are built around trick questions. Expect answers that break common sense, such as solutions that have nothing to do with the question as it first looks. Taking a moment to read the screen differently is the skill the game rewards.

What the puzzle format does well

The game is a long series of riddles and brain teasers, and the answers are often unexpected. That gives it a different feel from classic quizzes, where you simply recall facts. It also works as a trivia game to pass around: you can play alone or hand the phone to friends and argue over answers.

Session length is flexible. Each puzzle is a self-contained test, so you can solve one while waiting and stop. The description calls the play simple, and the format supports that, as there are no long tutorials to sit through.

Brain Test is also the first entry in a series. Brain Test 2: Tricky Stories, Brain Test 3: Tricky Quests, Brain Test 4: Tricky Stories and Who Is? Brain Teaser & Riddles continue the idea, so players who finish this one have an obvious next step. Google Play lists eight screenshots of the puzzle screens if you want a preview first.

Who should pick Geometry Dash Lite or Royal Kingdom instead

If you want reflexes and music rather than lateral thinking, Geometry Dash Lite is closer to that taste. Tiles Hop Music & Ball Game and Amaze GO! also lean toward action and quick rounds. Brain Test asks for patience and a willingness to be fooled.

Players who like building and progression should look at Gardenscapes, Royal Kingdom or Block Craft 3D: Building Game. Those titles reward long-term play with visible growth, while Brain Test is a string of separate riddles.

Also weigh the monetization. The game contains ads and in-app purchases, which can interrupt a calm puzzle session. Anyone who dislikes ads between levels may prefer a different genre or a paid puzzle title.
