hard

Brain Test 5 Level 70 is an electricity-routing level. Use the plus and minus poles to create the required blue powered shape on each grid, especially the side corridors and border fills around the black blocked bars.

Board Notes

Layout: Level 70 shows white grid boards cut by black blocked bars, with movable `+` and `-` poles below each puzzle. Correct pole placement turns the powered cells light blue.
Goal: Electrify the right parts of each board by routing power around the black blocked shapes.
Opening: The early boards teach the rule with a few poles and small blue corridors. The middle boards widen the powered areas around horizontal black bars, and the final board turns a tall black column into a large right-side blue rectangle with blue top and bottom borders.
Danger Zone: Random pole placement spreads power into the wrong lanes. The black bars are hard walls, so every plus and minus has to be placed with the obstacle geometry in mind.
Mechanics: Level 70 is a flow-routing puzzle. The poles stay the same, but the obstacle layout changes, forcing new blue shapes on every board.

Quick Tips for Brain Test 5 Level 70 (spoiler-free)

Build the powered shape from the black barriers outward.
Think of every black bar as a wall that the blue current must wrap around.
On the last board, the answer is a border-and-rectangle fill, not scattered blue cells.

How to Solve Brain Test 5 Level 70 — Full Solution

On the first boards, place the plus and minus poles so the blue power fills the intended side lanes without crashing into blocked bars.
Use the black obstacle shapes as walls and route the blue region around them.
On the larger middle boards, extend the powered shape through the long corridors instead of into dead ends.
On the final tall-column board, fill the big right-side blue rectangle and the top and bottom border strips around the black column.
Reposition any pole that creates the wrong blue route until the whole board matches the accepted powered pattern.

Common Mistakes to Avoid

Dropping poles at random and hoping the blue region lands correctly.
Forgetting that the black bars completely block the power path.
