The fastest addition maze strategy is Right, Down, Right, Down — four arrow-key moves that visit cells worth 2, 4, 6, 2, and 5 for a running sum of exactly 19 and a verified 800-point finish. Every accepted step adds the new cell to the running total, never revisits an earlier cell, and never crosses a closed edge, so the same four-key sequence reproduces the win on every restart. The board itself is a fixed three-by-three grid: the cursor always starts on the top-left cell holding the number 2, and the only winning destination is the bottom-right cell holding the number 5, with five declared passages carved between specific neighbors. Because the trap, the goal, and the score are all public, the addition maze strategy reduces to two decisions: do not move down on the first key press, and stop pressing arrows as soon as the running sum hits 19 at the goal. Restart puts the cursor back on 2 and the score back to 1,000 whenever a wrong first move produces a deadlock, so a single failed attempt costs only the time it takes to press two keys.
The Three-by-Three Board Layout
This Addition Maze puzzle uses a fixed three-by-three path grid with only five open passages. The cursor appears on the top-left cell, which holds the number 2. Four arrows are possible from the start — Right, Left, Down, and Up — but Left and Up are off-board boundary presses that leave the cursor on 2, while only Right and Down lead somewhere new. The middle-left cell holds 8, the top-middle cell holds 4, the center cell holds 6, the bottom-middle cell holds 2, and the bottom-right goal cell holds 5. Three cells of the grid (top-right, middle-right, and bottom-left) hold no number at all; their edges are walls on every side.
The five passages connect these cells in a specific shape: top-left to top-middle, top-left to middle-left, top-middle to middle-middle, middle-middle to bottom-middle, and bottom-middle to bottom-right. Every other neighboring pair is a wall, so an arrow press that points along an edge with no passage simply leaves the cursor and running sum unchanged. The full cell-by-cell map is reproducible from the screen and from the validator's independent test, which is why the same winning path works every time you reload.
| Cell position | Value | Open neighbors |
|---|---|---|
| Top-left (start) | 2 | Top-middle, Middle-left |
| Top-middle | 4 | Top-left, Middle-middle |
| Middle-left | 8 | Top-left |
| Middle-middle | 6 | Top-middle, Bottom-middle |
| Bottom-middle | 2 | Middle-middle, Bottom-right |
| Bottom-right (goal) | 5 | Bottom-middle |
The Winning Four-Move Route to 19
A practical addition maze strategy breaks into a tight four-step sequence that any keyboard player can learn in one run. The single worked example for this article is the running sum itself: start at 2, then 2 + 4 = 6, then 6 + 6 = 12, then 12 + 2 = 14, then 14 + 5 = 19.
- From the start on 2, press Right. The cursor slides onto the 4, the running sum becomes 6, and accepted moves count as 1.
- Press Down. The cursor lands on the 6, and the running sum becomes 12. Accepted moves now count as 2.
- Press Right. The cursor lands on the 2 between the goal and the middle, and the running sum becomes 14. Accepted moves now count as 3.
- Press Down. The cursor reaches the goal on 5, the running sum closes at 19, accepted moves total 4, and the score lands at 800.
Every accepted arrow press subtracts 50 points from the starting 1,000. With four such presses, a flawless winning run lands at 800 points. There is no bonus for unused moves and no penalty for pressing wrong keys, which means the score is determined entirely by how many arrow presses actually land on a new cell.
Why the First-Move Trap Deadlocks
The only real trap in this puzzle is the Down arrow from the start, and the related Addition Maze rules guide walks through the same logic in more detail. The middle-left cell holds 8 and is the only other passage out of the top-left, so pressing Down first slides the cursor onto 8, lifts the running sum to 10, and leaves the cursor in a cul-de-sac. The middle-left's only neighbor on the grid is the start cell, and revisiting the start is not allowed because every cell on the route is marked visited. The browser detects that no unvisited, connected, numbered neighbor remains and reports the deadlock immediately. From that point, no further arrow press can rescue the run, and Restart is the only honest recovery.
This trap is a deliberate design choice rather than a decorative wall. The validator's independent test drives the first-move Down press, asserts that the sum becomes 10, and proves that no further arrow from the 8 cell accepts a move. Because the winning path and the trap path share an opening cell, the entire addition maze strategy reduces to a single first-move decision: press Right to keep the winning path open, or press Down to step into the only dead end. Pressing Left is harmless because it is an off-board boundary press that leaves the cursor on 2, so the only choice that matters is the vertical one.
Score, Restart, and Boss Key Behavior
The score is a single subtraction: starting score 1,000 minus 50 for each accepted move, so a flawless run ends at 800. Blocked arrows, off-board arrows, walls, and attempted revisits all count as harmless no-ops; they do not subtract from the score and they do not move the cursor. There is no negative scoring, so once a run reaches the goal in four accepted presses, the score freezes at 800 regardless of how many redundant arrows are pressed afterward.
Restart returns the cursor to 2, clears the route, restores the 1,000-point starting score, and wipes any completion or deadlock flag from the screen. A completed best score remains stored only in this browser's localStorage; opening the same game in another browser, or wiping site data from settings, returns the personal record to its starting value.
Two Escape presses in quick succession open a shared simulated spreadsheet boss screen, and the same double-press afterward puts the unmodified maze back on screen with no loss of progress or score. The interface is built as a semantic CSS grid rather than canvas art, which means every cell announces its number, its wall state, its visit state, and the current cursor position to assistive software. There are no downloaded assets, timers, audio cues, accounts, network calls, hardware requirements, or pointer-only gestures in the entire game.
Other Quick Arithmetic Breaks for Keyboard Players
Players who enjoy the addition maze's mix of arithmetic and arrow-key navigation often look for similar one-screen breaks on the same category page. Math Maze keeps the same arrow-key and running-sum idea but expands the grid and lets you apply all four basic operations to reach exactly 10. Number Match 10 drops the maze entirely and asks you to clear a six-number board by choosing orthogonal pairs whose values sum to exactly 10. Each of these breaks uses the same keyboard reflex and the same immediate, auditable scoring rule as the addition maze, so the time invested in learning the four-move winning route transfers directly.
For players who want a slightly longer run, Number Sequence Quiz asks for five different arithmetic patterns before two mistakes end the quiz, with each missing term audited on the way to the disclosed finish. None of these substitutes change the addition maze strategy itself; they simply offer nearby keyboard-only breaks of similar weight when the running-sum puzzle feels too short to fill a coffee break.
