Brain Out Level 97

Overview

The prompt asks you to turn this pyramid upside down in three moves. Ten orange circles are stacked in an upright triangle: one circle on the top row, two on the second row, three on the third row, and four on the bottom row. Flipping the whole shape visually would be easy, but the level counts individual circle moves and limits you to three. The solution rearranges only the three corner circles: the top circle drops to the bottom point, and the two bottom corner circles rise to the sides of the new top row.

• Difficulty: Hard
• Estimated moves: 3

Step-by-Step Solution

1. Read the prompt and count the rows of the upright pyramid: one circle at the top, two below it, three in the next row, and four along the bottom. The target shape is an inverted triangle with four circles on top and one circle at the bottom.
2. Identify the three corner circles that need to change position: the single circle at the very top, the far-left circle on the bottom row, and the far-right circle on the bottom row. The inner circles stay where they are.
3. First move: drag the top circle down to the empty position below the bottom row, centered under the existing three-circle row. This becomes the new bottom point of the inverted pyramid.
4. Second move: drag the far-left circle from the bottom row up to the left side of the second row from the top, where it balances the new wide top.
5. Third move: drag the far-right circle from the bottom row up to the right side of that same second row.
6. Check the resulting arrangement: four circles form the top row, three sit in the next row, two in the next, and one circle points down at the bottom. A green checkmark appears on the inverted pyramid when the three moves are correct.

Strategy & Reasoning

A triangle of ten circles can be inverted by moving only its three corner pieces because the inner seven circles already sit in positions that match the flipped shape. The top corner and the two bottom corners are the only circles whose row and side change when the pyramid turns over. Moving any inner circle would waste one of the three allowed moves and leave the shape unbalanced.

Trying to flip the board itself or rotate the screen does not work; the level tracks circle positions, not orientation. Counting rows before moving helps you see that the wide row must migrate from the bottom to the top. The three-move budget forces a minimal rearrangement, and the corner-to-corner swap is the shortest way to turn the upright stack into a downward-pointing triangle.

Tips & Common Mistakes

• Move only the three corner circles; shifting an inner circle uses up a limited move without helping the shape.
• Drop the top circle straight down to the new bottom point before raising the two bottom corners to the sides.
• Verify the row counts after the moves: four on top, then three, two, and one at the bottom; if the checkmark does not appear, reposition a corner circle rather than moving an inner one.
