Brain Test Level 78 Answers
“How many cubes are there”
Level 78 Answer
The puzzle: How many cubes are there
There are 9 cubes on each other if you think of the cubes in 3D and there is also another hidden cube on the left side of the screen. There are in total 10 cubes.
How Level 78 Breaks Down
This page solves Brain Test level 78, part of Levels 1-475, which asks “How many cubes are there”. The solution above is the action that clears it, written out rather than hinted at.
Brain Test levels are trick questions: the answer is rarely the obvious reading of the words on screen, and often needs you to drag an object, tilt the phone, or use part of the interface the puzzle did not point at. That is why the solution is a sentence and not a word — there is nothing to spell.
Step to level 77 or level 79, browse Levels 1-475, or return to the Brain Test hub, which indexes 474 levels.
The solution here comes from the live game rather than another answers site, and is re-checked whenever the developer updates a level. Level numbering shifts when Unico Studio inserts new puzzles, so if the question above does not match what is on your screen, check the level either side before assuming the answer is wrong.
If an answer here stops matching what you see on screen, the game has most likely been updated: leave a comment below and it gets looked at. Reader reports are usually how a changed puzzle is spotted first. You can also browse the rest of Brain Test from the hub, which indexes every level we hold, grouped the same way as this one.

3 Tips for Brain Test
The board is the whole puzzle
Every answer is built from what the level actually shows you and nothing else. Counting that first rules out most of what comes to mind, which is quicker than trying words and being rejected.
Place the longest answer first
Long answers use up the awkward letters and leave a set that spells the short ones out for you. Starting long is consistently faster than sweeping for three-letter words.
Neighbouring levels are the best hint
Difficulty climbs gradually rather than in jumps, so the levels either side of a hard one reuse its patterns. They are more useful than any hint the game sells you.
How to Solve a Brain Test Level
The order that clears a board fastest.
Read what you are given
Letters, tiles or clues — count them before you start. That constraint is the strongest filter you have.
Anchor with the answers you are sure of
Each confirmed answer narrows the ones it touches, so the easy entries are worth the first minute.
Work outwards
Follow the chain from what you have placed rather than jumping around the board.
Verified Answers, Not Guesses
How we verify these answers
Every answer on this page is read from the game's own puzzle data rather than retyped from another site, and is checked against what the board actually provides — so nothing listed can use a letter the level does not give you. The counts shown are computed from the stored data, not typed in by hand.
