Game Is Hard Level 100 Walkthrough: Lights Out Grid

Level 100 is the game's take on the classic "Lights Out" puzzle — but with three states instead of two. A grid of shapes (circles, triangles, and squares) fills the screen, and tapping any cell cycles its own shape while also cycling its neighbors. The goal is to get every cell to land on a circle, which turns out to be a lot harder than it sounds because every fix ripples outward.

⚡ Quick Answer

Tap cells to cycle shapes — a tap advances the tapped cell and its neighbors one step through circle → triangle → square → circle. Work the board until every cell is a circle. Fix cells in an order that lets later taps clean up the earlier ripples.

Game Is Hard Level 100 Breakdown

What You See

A grid of tiles, each holding one of three shapes: circle, triangle, or square. The starting board is a messy mix, with no obvious button or instruction beyond "make them all the same." Tapping a tile visibly flips that tile and several around it in a burst of change.

Why You're Stuck

I'd line up a few circles in one corner, feel great, then tap the next tile and watch the whole corner scramble again. That's the core frustration: you can't solve this cell-by-cell because every tap rewrites its neighbors. I was playing checkers when the game is chess — each move has consequences you have to plan around.

The Answer

Cycle every tile to a circle by tapping strategically. A tap advances the tapped tile and its four neighbors one step in the cycle (circle → triangle → square → circle). The solve is a sequence of taps that steers the whole board to circles without undoing finished areas.

How to Beat It

  1. Learn the cycle: circle → triangle → square → circle. Each tap advances the tile and its up/down/left/right neighbors one step.
  2. Start in a corner and push a row of circles across the board.
  3. Use the second-to-last row to fix the bottom row — because a tap there only spills into neighbors you've already planned for.
  4. Sweep top to bottom, then patch any stragglers with single corrective taps.

Troubleshooting

  • Everything keeps unscrambling: you're fixing cells in a random order. Move in a consistent sweep and use edges as your boundary.
  • One stubborn square won't clear: tap its neighbor instead of the square itself — the ripple may land it correctly.
  • Lost track of the cycle: remember it's three states, so a square needs two advances (or one from triangle) to become a circle.

Why It Works

The puzzle is "Lights Out" generalized to three states, which is why it feels so punishing: instead of a simple on/off toggle, every cell has a three-position dial that keeps rotating. The winning strategy is the same one that beats classic Lights Out — process the board in a fixed sweep and let the second-to-last row act as your control surface for the last row. Once you treat the tap as a dial-turn that spreads, the chaos becomes a solvable system.

The Rule to Carry Forward

In ripple puzzles, order beats brute force. Move in one direction and fix each row using the row below it, so no finished work ever gets re-scrambled.

  • Know the state cycle before you start — count the steps between each shape and the target.
  • Work top-to-bottom (or left-to-right) so corrections only spill forward into unsolved space.
  • Leave yourself a control row — the penultimate row/column is where you clean up the final line.
Pro tip:

Don't tap a cell that's already a circle unless its ripple is what you actually need — every tap changes five cells at once.

Common mistake:

Whack-a-mole. Fixing tiles at random guarantees you'll re-break the ones you already solved.

Game Is Hard Level 100 FAQ

How do I solve the shape grid in Game Is Hard Level 100?

Tap shapes to cycle them — and their neighbors — through three states (circle, triangle, square) until every cell on the board is a circle.

Why do neighboring shapes change in Game Is Hard Level 100?

It's a Lights Out style cascade. Tapping one cell also advances its up/down/left/right neighbors, so you must manage the ripple effects rather than fixing cells one at a time.

What's the target state in Game Is Hard Level 100?

Circles. The board starts as a mix of circles, triangles and squares, and the level completes only when every cell reads as a circle.
