Smart Grid Solver
How to Play Smart Grid Solver
Smart Grid Solver is a minimalist, physics-inspired logic puzzle where you take on the role of a grid engineer. Your mission is to restore power to a malfunctioning network by rotating disconnected wire nodes until every single one is linked back to the central energy source.
The Objective
You are presented with a grid of scrambled wire tiles. Your goal is to rotate these tiles to form an unbroken, perfectly sealed network. You win the level when every single node on the board is “Powered” (turning from dark slate to glowing cyan) and there are no “loose ends” leaking energy into the void.
Official Rules
The game relies on precise connection logic and flow mechanics:
- The Power Source (⚡): Located in the center of the grid, the source tile is always powered and glows with a purple-and-cyan gradient.
- Rotating Tiles: Every tile on the board can be rotated 90 degrees clockwise with a single tap or click.
- Power Flow: Power only flows between tiles if their wire openings line up perfectly. For example, if a tile has a wire pointing Right, the tile to its right must have a wire pointing Left to receive the charge.
- Powered State: When a tile is successfully connected to the source, its wires will light up in a glowing cyan color.
- The Win Condition: To complete a level, two conditions must be met:
- All nodes must be connected to the power source.
- No loose ends: Every wire must point to another wire; no wire can point toward an empty edge or a flat side of an adjacent tile.
Understanding the Node Types
Different tiles provide different connection possibilities:
| Node Type | Description |
| Dead-end | A single wire that terminates at a node point. |
| Straight | Connects two opposite sides in a direct line. |
| L-bend | A 90-degree corner piece used to turn the flow. |
| T-shape | A three-way junction that splits power in multiple directions. |
| Cross | A four-way intersection connecting all adjacent tiles. |
Top Strategies to Win
Start from the Corners and Edges
Tiles on the edges and corners have the fewest possible valid orientations because wires cannot point off the board. Start by rotating these tiles so their wires face inward. This often “forces” the correct orientation for the inner tiles.
Trace the Flow from the Source
Work outward from the central ⚡ source. Since you know the source is always providing power, ensure the tiles immediately adjacent to it are aligned correctly first. A solid foundation at the center makes it much easier to branch out.
Eliminate Impossible Connections
If you see a tile with a flat side facing an adjacent tile’s wire, you know one of them must be rotated. Use the process of elimination to identify tiles that only have one logical orientation.
Watch Your Moves
While there is no move limit, the game tracks your efficiency.
- 🌟 Perfect!: Solving the level in a number of moves equal to or less than the total number of tiles ($N \times N$).
- ⭐ Excellent!: Solving the level in under double the number of tiles.
