How to play Pressure Grid
Pressure Grid is a compact logic game about reading connections rather than matching colors. Every board contains a source, an exit, and a network of straight pipes, corners, junctions, and fixed endpoints. The pieces begin in deliberately unhelpful orientations. Your job is to rotate the movable tiles until flow can travel from the source through every required section and reach the exit without leaking into a dead end.
A good run starts with structure. Fixed endpoints and edge tiles reveal which directions are impossible, while three-way junctions often determine the orientation of an entire region. You can solve locally, but the final route is global: a connection that looks correct in one square may force a contradiction several tiles away. The move counter rewards planning, and the timer adds pressure without turning the puzzle into a reflex test.
Three difficulty settings change the size and density of the network. Easy is suited to learning the pipe language, Medium introduces more competing branches, and Hard asks you to manage a broad board with fewer obvious anchors. Each generated layout is intended to be solved as a fresh deduction problem, so restarting is useful practice rather than a way to memorize a single answer.
Controls

| Gamepad | Not available | Use mouse, touch, or keyboard for this build |
Rules and objective
- Connect the source to the exit and include every required pipe segment in one leak-free network.
- Fixed source and exit pieces cannot be rotated; use them as the first constraints when reading a board.
- A pipe opening that points off the board or into a closed side is a leak and prevents completion.
- The puzzle completes only when the full network is valid, not when one partial path happens to reach the exit.
Scoring and progression
- Moves
- Every clockwise or counter-clockwise rotation adds one move. Lower totals show a more efficient solve.
- Time
- The clock runs from the start of the board until the entire network is connected. Faster solves improve the result.
- Difficulty
- Larger settings contain more cells and competing connections, so compare results within the same difficulty.
- Best result
- The game records its best completed run locally in the browser when storage is available.
Modes and features
- Easy
- A smaller board with fewer intersections, designed to teach the connection rules.
- Medium
- A broader network with more junctions and less obvious edge information.
- Hard
- The densest board, built for deliberate route tracing and efficient move counts.
- Fresh boards
- Generate another layout without leaving the page, or reshuffle the current network for a new orientation challenge.
Tips for a better run
- Begin at the fixed source and exit, then mark the orientations they force on neighboring tiles.
- Resolve corners along the outer edge early; two of their four rotations point outside the grid and can be eliminated immediately.
- Do not rotate a junction just because one branch fits. Check all of its openings against the surrounding region first.
- When the board is nearly solved, trace the network from the source instead of scanning random tiles. The first break usually identifies the remaining mistake.
From the workbench
Gigabite built Pressure Grid as a quiet counterpoint to the reaction-heavy games in the arcade. The visual feedback separates connected flow from merely adjacent pieces, while two-way rotation keeps correction from feeling punitive.
