About the game
One picture or one row of shapes, one answer to give. Brain Test: IQ Challenge mixes three kinds of short tasks: noticing what changed between images, choosing the object that does not fit, and working out what comes next in a sequence. Hundreds of levels are there to work through, and a hint costs nothing when a puzzle refuses to crack. Tap your pick, the next one loads.
How to play
- Study the puzzle, then tap the difference, the odd object or the piece that completes the pattern.
- Open a free hint on any level that leaves you stuck.
- Clear one puzzle at a time and keep going through the hundreds of levels.
