Brain Out 2 Level 117
📝 Walkthrough
Overview
Level 117 says "Let the seesaw move!" A seesaw is stuck: on the left, a heavy pink elephant sits on the lowered end, while on the right a small girl sits helplessly on the raised end, straining in vain. Below the seesaw lie three objects: a red mushroom, a gray handbag that looks like a heavy weight, and a backpack. The victory line, "Moved briefly...", appears after the board finally tips.
- Difficulty: Regular
- Estimated moves: 2
Step-by-Step Solution
- See why it is stuck. The elephant is far heavier than the girl, so the elephant end stays on the ground and the girl's end will not budge.
- Inspect the loose objects. Below are a mushroom, a gray handbag/weight, and a backpack.
- Add weight to the light side. Drag the heavy objects — the gray handbag (weight) and the backpack — onto the girl's end of the seesaw.
- The balance tips. With extra weight on the girl's side, her end sinks down and the elephant's end rises.
- Confirm. The seesaw flips, with the girl now low and the elephant lifted up. The screen says "Moved briefly..." and the level is cleared.
Strategy & Reasoning
This is a balance/leverage puzzle. The seesaw cannot move because the elephant's mass completely overwhelms the girl. Merely having the girl push or bounce does nothing, because the weight difference is too extreme.
The solution is to add counterweight to the light side. Among the objects, the gray handbag looks like a solid heavy weight and the backpack is also load-bearing; the mushroom is a tiny, light distractor. By piling the heavy items on the girl's end, you increase her side's total weight until it overcomes the elephant and the board finally teeters.
The humor is that even a whole elephant can be briefly out-tipped by a bag and a backpack. The lesson is to rebalance the lever by adding mass to the light side rather than trying to move the elephant itself.
Tips & Common Mistakes
- Mistake: telling the girl to push. Her strength cannot counter an elephant; pushing does nothing.
- Mistake: dragging things to the elephant. That only makes the heavy side heavier and wedges it further down.
- Mistake: using the mushroom. It is light and a distractor. Put the gray weight/handbag (and backpack) on the girl's raised end until the seesaw tips.
Walkthrough Notes
The elephant is far too heavy for the small girl, so adding more weight to the girl's side does not work. The trick is to remove weight from the elephant's side instead. The handbag that looks like a heavy weight is actually the thing to take away, or the red mushroom distracts the elephant. Once the load on the left is reduced, the board tips. The victory line "Moved briefly..." confirms it. Compare this with piling objects on the right: the elephant still outweighs everything. Reducing the left side is the counterintuitive move.
