Water Flow Puzzle is a guide-the-water game played on five fixed 7 by 7 boards where you dig up to five channels from a single top source so a synchronous, priority-driven flow reaches a bottom container and captures exactly six particles per level. Each board offers eight visible soil cells that you can open, a source on the top row, a container on the bottom row, and rock cells that cannot be toggled. A successful run clears all five levels for 200 points each, finishing on an exact 1,000-point total that is recorded when you press Finish Game. The puzzle is fully deterministic: the same five-cell layout always follows the same ordered path, so the only variable is which cells you choose to dig and in which order you press Release Water.
What "guide the water game" actually means here
When players search for a guide the water game, they usually want a short, skill-based puzzle with a clear single win condition rather than a long physics sandbox. Water Flow Puzzle fits that intent because the goal is narrow and explicit: connect the source to the container with a layout that the rules can follow. Each board is a tiny 49-cell grid, every interior cell except the eight diggable soil cells acts as rock, and the budget for opening new channels is fixed at five. There is no timer, no random source position, no shifting obstacle, and no hidden mechanic that triggers after Release. The flow evaluates the entire route the moment you press Release Water, and the path shown on the board is the path the rules actually evaluated.
That compact design makes Water Flow Puzzle easy to read at a glance. A new board immediately tells you where the water starts, where it must end, and which cells you are allowed to dig. From that information alone you can reason about the layout without guessing about pressure, viscosity, or pipe diameter, none of which apply to this puzzle. The word water is a visual theme for a cellular routing puzzle, and the movement rules are deliberately compact so that the same five-cell solution works identically on a fast laptop, a slow tablet, or a background browser tab.
The fixed flow priority: down, down-left, down-right
The movement rule is the heart of the puzzle and is fully visible in the released path. From its current cell, water first looks straight down. If the cell directly below is not an open channel, the flow then checks down-left, and finally down-right. The first open channel encountered in that strict order becomes the next cell. Before the last row, if none of those three candidate cells is open, the flow stops and the run is recorded as a blocked path with zero points. On the final channel row, only the cell directly above the container captures all six particles; any other final column sends the water through the bottom as a leak, also with zero points but with a different message so you can tell an incomplete route from a wrong exit.
| Step | Order checked | Direction | If open, water moves here |
|---|---|---|---|
| 1 | First | Straight down | Only down is followed |
| 2 | Second | Down-left | Only when down is rock or closed soil |
| 3 | Third | Down-right | Only when both down and down-left are blocked |
| Final row | Directly above container | Vertical drop into opening | Captures all six particles |
| Final row, off-center | Another final-row column | Out the bottom edge | Leaks, captures zero |
Because the priority never changes, a layout that looks like it should reach the container can still leak sideways if the rule redirects the flow one step earlier than you expected. This is exactly the same kind of single-rule thinking used in puzzles such as Maze Game and Numberlink Puzzle, where a deterministic grid rule overrides any visual intuition that ignores the priority.
Dig the right five cells: a step-by-step route
The single best way to plan a board is to start from the container and work backward along the priority rule. Because water only ever goes down, down-left, or down-right, every step of the captured path must be one of those three moves, and the cell directly above the container must be open or no path can finish vertically.
- Identify the container's column on the bottom row and mark the cell directly above it as mandatory: it must be open or the flow can never enter the tank.
- Trace a path upward from that mandatory cell using only down, down-left, and down-right moves in reverse, asking at each cell whether the forward priority would reach the next one.
- Toggle soil cells one at a time using the board controls. Each soil cell toggles between closed soil and open channel, and a sixth open cell is rejected without changing the board, so the budget is enforced atomically.
- After opening at most five channels, press Release Water. The game evaluates the synchronous flow from the source through your submitted set in the same priority order on every device.
- Read the container report. A 6/6 capture means every particle reached the vertical opening and you earned exactly 200 points; a blocked or leaking result means the path never reached the container and you earned zero.
- If the run failed, study the rendered particle path to see where the priority diverted the flow, toggle one or two cells, and press Release again. Repeatedly releasing an identical failed layout preserves one recorded failure; releasing a second different failed layout deadlocks the run and requires Restart.
Editing after the first failure keeps the failure history but clears the old path display, which makes it easy to compare the new attempt against the previous route. Once you capture 6/6 particles on a level, the success state stays visible until you press Next Level, giving you time to inspect the actual flow path and the 200-point award before the board changes.
Scoring, leaks, blocked runs, and failure history
Each level awards exactly 200 points for capturing all six displayed particles, and the fifth success records an exact 1,000-point completion when you press Finish Game. A blocked path and a leaking path both capture zero, but they receive different messages so you can tell an incomplete route from a wrong bottom exit. Every failure uses a normalized layout signature, which is the sorted set of open channel cell indices, so the order in which you dig the same layout does not create a new recorded failure. Releasing an identical failed layout a second time still counts as one failure. Releasing a second, different failed layout deadlocks the run and forces a Restart that recreates the initial level-one board without changing the level or score state.
The five boards were authored specifically for this product, and an independent literal oracle stores one five-cell solution for each level without importing a solution marker from the production level table. Tests exhaust every subset of each level's eight diggable cells up to the five-cell budget and prove that exactly one layout captures the required water, removing any solution cell fails, and separate fixtures pin a blocked route and two bottom leaks. The production level objects hold source, target, diggable cells, and budget only, which means the correct subset is never marked in the DOM, accessible labels, or test attributes; only a real Release evaluates the chosen channel set.
Controls, accessibility, and what runs in your browser
Mouse and touch players tap soil cells and press Release Water; each interactive soil cell is at least 44 by 44 CSS pixels and the seven-column board fits within a 320-pixel width on a 390-pixel mobile viewport. Keyboard players Tab through the eight real soil-cell buttons, press Enter or Space to toggle a channel, and Tab again to reach Release, all of which rely on native focused buttons rather than a page-wide listener, so arrows and activation keys on other controls keep their standard behavior. This keyboard route is similar in spirit to the deterministic controls in Sokoban and Pipes Puzzle, where every move and rotation is bound to a real button that announces its state.
Everything runs in the browser. Channel layouts, flow paths, failures, and scores are not uploaded, and no account, paid service, network calculation, package dependency, sensor, or file access is required. The shared game shell may store the best completed score locally when browser storage is available, and blocked storage simply removes that convenience without affecting play.
