Game Is Hard Level 105 Walkthrough: Water Displacement

Level 105 puts a ball on a little platform above a tank of water, with the instruction "don't let it sink." Three square blocks sit around the tank looking decorative. The physics is the actual puzzle: dropping those blocks — and the platform itself — into the water raises the water level, until the ball can float safely on top. It's an Archimedes lesson in game form.

Level 105 is water displacement — drop all four blocks. Prefer YouTube? Watch it there →

⚡ Quick Answer

Drop all four blocks into the water: the three squares around the tank, plus the platform under the ball. The water rises with each block, and by the fourth the ball floats on the elevated surface.

Game Is Hard Level 105 Breakdown

What You See

A glass tank half-full of water, a ball resting on a small square platform above it, and three more square blocks sitting outside the tank. The instruction is "don't let it sink." The blocks look like background clutter, but they're the only tools you have.

Why You're Stuck

I treated the three external blocks as scenery and kept poking at the ball, expecting some kind of button or secret tap. The real move is counter-intuitive: you have to remove the ball's own platform — the thing keeping it "safe" — and drop it, because the platform is itself a displacement block. I was protecting the ball when the answer was to drop its support and let the rising water catch it instead.

The Answer

Submerge all four blocks. Tap each of the three square blocks to drop them into the tank, then tap the platform under the ball to drop it too. The cumulative displacement raises the water until the ball floats.

How to Beat It

  1. Tap the left square — it falls in and the water rises a little.
  2. Tap the upper-right square, then the lower-right square — three blocks submerged.
  3. Tap the platform under the ball — it drops in, the ball briefly falls, then settles on the now-high water.
  4. Confirm the ball is floating, and the level clears.

Troubleshooting

  • Ball still sinks: you're missing the fourth block — the platform itself. It must also be dropped.
  • Only dropped three blocks: that's not enough water; the platform is the final displacement.
  • Ball bobs after a shake prompt: the shake is just celebration — once four blocks are in, the ball is already floating.

Why It Works

The level teaches displacement through a bait-and-switch. The platform looks like it's protecting the ball, but it's actually a submerged block waiting to be used. Every object you add to the water pushes the surface higher, so the "dangerous" move — removing the ball's support — is what finally raises the water enough to keep the ball afloat. The physics is real, and the puzzle is trusting it over your protective instinct.

The Rule to Carry Forward

In a "don't let it sink/fall" puzzle, consider dropping the support itself. Objects that look protective may be the very weight that raises the water level.

  • Count every movable block — if three don't do it, the fourth (the platform) is the missing piece.
  • Trust displacement — more submerged mass means a higher surface, not a sunken ball.
  • Question the "safe" object — in Game Is Hard, what protects is often what must be sacrificed.
Pro tip:

The waterline is your progress bar. Watch it rise after each drop — it tells you exactly how many more blocks you need.

Common mistake:

Leaving the platform under the ball in place. It's the fourth block, and without it the water never rises enough.

Game Is Hard Level 105 FAQ

How do I float the ball in Game Is Hard Level 105?

Drop all four blocks into the water: the three squares outside the container, plus the platform block the ball is sitting on. Displacing the water raises its level enough for the ball to float.

How many blocks do I drop in Game Is Hard Level 105?

Four. Three square blocks sit outside the container, and the fourth is the platform directly under the ball. All four must be submerged.

Why does the ball sink when I remove its platform in Game Is Hard Level 105?

It drops for a moment when the platform is removed, but by then the four submerged blocks have raised the water level, so the ball lands on the elevated surface and floats.
