Yes, you can solve Water Flow Puzzle with a keyboard: press Tab to focus a soil-cell button, press Enter or Space to toggle it, then Tab to Release Water.
The game uses native focused buttons rather than a page-wide keyboard listener. You select the cells that should become channels, and the game calculates the entire route from that layout when you release the water.
Keyboard controls for Water Flow Puzzle
Each of the five fixed 7 by 7 boards contains eight visibly diggable soil cells. Tab moves focus among the real soil-cell buttons, while Enter or Space toggles the focused cell between closed soil and an open channel. Arrow keys are not used to steer the flow.
| Task | Keyboard control | What happens |
|---|---|---|
| Choose a soil cell | Tab | Moves browser focus to the next soil-cell button. |
| Open or close that cell | Enter or Space | Toggles the focused soil cell between closed soil and an open channel. |
| Reach the release control | Tab until Release Water has focus | Moves focus from the grid controls to the release button. |
| Evaluate the route | Enter or Space on Release Water | Calculates and displays the complete deterministic flow. |
Rock cells, the source, and the container cannot be changed. They are therefore not part of the digging decision. Every interactive soil control is at least 44 by 44 CSS pixels, and the seven-column board fits within a 320-pixel width for a 390-pixel mobile viewport.
Keep the keyboard focus on the board rather than expecting arrow-key movement. A water route is built by opening the correct cells, not by moving a sprite around the grid.
Solve a Water Flow Puzzle board with the keyboard
- Read the fixed terrain. Find the source on the top row and the container on the bottom row. Identify the eight soil cells that can be opened; the other interior cells act as rocks.
- Focus the first soil button. Press Tab until a soil cell receives keyboard focus. Continue using Tab to inspect each of the eight diggable cells.
- Open the intended channels. Press Enter or Space on each focused soil cell that belongs in the route. The cell changes between open channel and closed soil, so pressing the activation key again closes it.
- Stay within the digging budget. Open no more than five cells. If you attempt to open a sixth, the game rejects that action without changing the board.
- Check the branch order. From each current cell, the water prefers down, then down-left, then down-right. Make sure the first open candidate in that order is the branch you intend it to follow.
- Check the final approach. The path must reach the final channel row directly above the container’s opening. A route ending in another column on that row will leak through the bottom.
- Release the water. Tab to Release Water and activate it with Enter or Space. The game calculates every move synchronously and shows the path that its rules actually evaluated.
- Read the result. A captured route displays a 6/6 container result and awards 200 points. A blocked or leaked route captures zero. After the first failed layout, inspect the displayed path before making a careful revision.
If the route succeeds, the result remains visible until you choose Next Level. On the fifth successful level, Finish Game records the completed 1,000-point result.
How the keyboard-selected route is calculated
Water Flow Puzzle is a synchronous cellular routing game, not a decorative success animation. At every step, the engine checks three possible destinations in a fixed order: straight down first, down-left second, and down-right third. The first open channel in that order becomes the next cell.
That priority matters when several branches are open. Opening a lower-priority cell does not cause water to ignore an available cell above it in the priority order. The route follows the first eligible opening, so every selected channel must belong to the intended deterministic path.
If none of the three possible destinations is open before the last channel row, the route is blocked. On the final channel row, only the cell directly above the container has a vertical opening that captures the water. Reaching another column on that final row sends the particles through the bottom as a leak.
For a deeper explanation of the grid route, see the guide to routing six particles across a 7 by 7 board. The keyboard does not change the route rules: the same open-cell layout always produces the same ordered path.
There is no random source, hidden timer, changing obstacle, or frame-rate-dependent result. Mouse, touch, and keyboard submissions agree because the board state and submitted channel set determine the outcome. The “water” is a visual theme for a grid game, not a calibrated simulation of pressure, gravity, pipe capacity, or other hydraulic behavior.
Tell a blocked route from a bottom leak
| Result | Route condition | Score result |
|---|---|---|
| Captured | The evaluated path reaches the container through the cell directly above its opening, and the container reports 6/6. | Level clears for exactly 200 points. |
| Blocked | Before the final channel row, none of the down, down-left, or down-right candidates is an open channel. | Zero particles are captured. |
| Leaked | The path reaches the final channel row in a column other than the one directly above the container. | Zero particles are captured. |
Blocked and leaked routes both score zero, but the game gives them different messages so you can identify the problem. If the result says the path is blocked, inspect the final open cell before the bottom row and check whether the first available candidate has been closed accidentally. If it says the water leaked, trace the last step and confirm that the route enters the container’s column rather than another final-row column.
The displayed result is useful after release because it shows the path the engine evaluated rather than an unrelated preview. Each flowed channel carries visible particle dots, while the container itself reports 6/6 only when the vertical opening captures all six particles.
Plan before Release because failed layouts are limited
The retry policy is the main limitation to keep in mind while solving with a keyboard. A failed attempt is stored as a normalized layout signature: the sorted set of open channel cells. Therefore, opening the same five cells in a different order does not create a different failed attempt.
- Releasing an identical failed layout again preserves the single recorded failure rather than adding another distinct failure.
- Editing after the first failure keeps that failure history, although it clears the old path display.
- Releasing a second different failed layout deadlocks the run and requires Restart.
- A successful layout clears the failure history before the next fixed level begins.
Restart recreates the exact initial level-one state, so it does not merely reopen the current board. That makes it important to check the branch priority and final approach before using Release Water a second time on a revised layout.
Each authored level has exactly one capturing five-cell layout. Trial-and-error can still reveal a mistake, but the second-distinct-failure rule makes careful deduction more useful than repeatedly submitting several unrelated guesses.
Complete the five levels for 1,000 points
A level is cleared only when all six displayed particles reach the container. That success awards exactly 200 points, and success stays visible while you inspect the path, particle markers, 6/6 result, and score. Choosing Next Level begins the next fixed board; the fifth success presents Finish Game and records exactly 1,000 points.
Once a board is captured, inappropriate edits and releases are frozen until you advance. Deadlocked states also freeze further actions until Restart is used. This prevents an accidental keypress from changing a completed or terminal board.
Everything runs in the browser. No account, paid service, network calculation, package dependency, sensor, or file access is required. Channel layouts, flow paths, failures, and scores are not uploaded; the shared game shell may store the best completed score locally when browser storage is available.
