When you finish the fixed 5 by 5 Star Battle puzzle on this page, a valid complete board awards exactly 1,000 points. That number is not a placeholder, not a default, and not affected by how long you take, how many times you restart, or whether you happen to be offline. The score is a single fixed reward that fires once the Check action confirms your 25-cell decision matches the one unique placement the puzzle accepts. To understand why the number is locked, it helps to separate the three pieces behind it: the rules the board enforces, the solver that proves only one placement is legal, and the two-strike Check flow that decides whether your attempt counts.
What "Exactly 1,000 Points" Means in Practice
The 1,000-point reward is a deterministic final-state result. There is no time bonus, no streak multiplier, no hidden bonus, no random event, and no network call that could change it. Once your Check action validates a complete board against the unique solution, the controls freeze and the score display reads 1,000. The reward is the same on a phone, on a tablet, on a laptop, in a private window, or on the same device after a refresh, because the board, the rules, and the answer are all encoded into the page itself.
This is also why the score is independent of how you arrived at the answer. You can solve it by pure logic over twenty minutes, by trial and error across a dozen restarts, or by typing the disclosed coordinates in one move; the score still reads 1,000. Completion does not depend on elapsed time, random generation, hidden bonuses, or network state. The reward only means the one fixed board matched its deterministic rules before the second invalid complete attempt.
How the Check Action Decides Your Fate
Checking follows a deterministic two-strike flow that protects incomplete thinking while still holding wrong answers accountable. The sequence below describes exactly how your attempt is judged and what each outcome does to your run.
- If any cell is still unknown when you press Check or hit Enter, the game reports that the board is incomplete and leaves the mistake counter unchanged. A half-finished thought never counts as a failed attempt.
- If every cell is decided but at least one rule is violated, the game consumes one mistake and the board remains editable. You get a chance to repair a mistaken deduction without losing the run.
- If a second invalid complete check happens, the run deadlocks and you must choose Restart to play again.
- If the complete board matches the unique solution, the controls freeze and exactly 1,000 points are awarded.
The two-strike window is what makes the 1,000-point reward feel earned rather than lucky. You are allowed one repair pass so that a single misread of the region borders or a single forgotten diagonal does not waste the run, but two fully decided mistakes mean the run is over. Restart always returns to the same original region map with all 25 cells unknown, zero mistakes, zero score, and the first cell selected, so the same opportunity is available on every fresh start.
Why the Board Has Exactly One Solution
For the 1,000-point reward to mean anything, the puzzle has to accept exactly one answer and reject every other placement, however close. The page proves that with an independent bounded backtracking solver that does not trust the stored answer at face value.
The solver walks the board row by row because the rules require one star in every row. For each candidate cell, it rejects a column or region that has already been used and rejects any cell whose column is adjacent to the previous row's star, which covers vertical and diagonal touching between neighboring rows. When all five rows are placed, a separate validator recounts every row, column, and region and checks every pair for king-move adjacency. The search is capped at two answers, then required to be exactly one. For this fixed region map, the solver finds one and only one solution, so the five legal star coordinates are stable across every visit and every device.
The disclosed coordinates — row 1 column 1, row 2 column 3, row 3 column 5, row 4 column 2, and row 5 column 4 — satisfy every row, column, and region count of one and pass the no-touch check on the local adjacency rule. Independent tests confirm that the five coordinates give counts of one across all rows, columns, and regions, and they also exercise horizontal, vertical, and diagonal contact failures, plus a pair farther apart on a diagonal that remains legal under the local adjacency rule. None of this analysis runs while you play, so the game surface does not reveal the answer; it only reveals that your Check matched the same unique placement.
The Five-Region Board the Score Is Built On
The score is tied to the specific region map encoded into this page, not to the abstract Star Battle ruleset. The map is a 5 by 5 grid with five irregular outlined regions labeled A through E by a small letter in each cell. Region A has two cells, B has eight, C has two, D has five, and E has eight. The unequal shapes create the deductions; region size does not change the requirement of exactly one star.
| Region | Cell count | Constraint it adds to scoring |
|---|---|---|
| A | 2 | Tiny region forces an early star placement and a small set of legal rows. |
| B | 8 | Largest region; absorbs the most placement options and constrains its neighbors. |
| C | 2 | Small region that mirrors A and pins down a specific row and column. |
| D | 5 | Mid-size region shaped to interact with B and E across their shared borders. |
| E | 8 | Largest region; paired with B to balance the board and split the remaining columns. |
Every cell belongs to one and only one region, and every region is connected through shared sides rather than isolated pieces. Automated invariants verify 25-cell coverage, five non-empty region IDs, the expected region sizes, and orthogonal connectivity for every region. Because the map is original to this page rather than lifted from the World Puzzle Championship booklet, Puzzle Star Battle, a newspaper, or a puzzle book, the unique solution here is a property of this specific product fixture, not a generic property of Star Battle puzzles. Change a region border and the answer would change; the 1,000-point reward is the score for solving this map.
What the 1,000-Point Score Does and Does Not Measure
The 1,000-point result only means that the one fixed board matched its deterministic rules before the second invalid complete attempt. That is a deliberately narrow definition, and it is worth being explicit about what falls outside it.
The score does not measure how smart you are, how fast you reason, how well you focus, how strong your memory is, whether you are ready for school, how your visual processing compares to anyone else's, or anything about your health. It does not produce a percentile, a ranking, a label, or a diagnosis. Repeating the puzzle to push the score higher is repetition of the same answer, not a measure of improving skill, and once you remember the coordinates the exercise becomes a rehearsal of the interaction and rule structure rather than a comparison of performance. The 1,000 points are a clean completion signal for a recreational logic puzzle, not a standardized test result.
Inputs and State That Affect Whether You Reach 1,000
Reaching the score depends on a handful of interacting limits and inputs that the page enforces, and missing any one of them keeps the run short of 1,000.
- All 25 cells must be decided as either star or empty before Check will judge the placement. Unknown cells trigger an incomplete message and never consume a mistake.
- Every row, column, and region must contain exactly one star when the board is complete. Two stars in the same row, column, or region make the board invalid and start the two-strike countdown.
- No two stars may touch by a side or corner. King-move adjacency is the rule; longer shared diagonals are not automatically banned, so two stars two rows and two columns apart remains legal.
- Each cell is one of three explicit states — unknown, star, or empty — and the page keeps the current state visible so your reasoning does not disappear between moves.
- The Check action is local to the browser tab. No server call, no upload, no account, and no network state is required to receive the score.
If every one of these interacting limits holds, the 1,000-point reward fires once and the run is over. If any one breaks, the Check action either reports an incomplete board, consumes one mistake, or deadlocks the run after the second invalid complete check. The boss key, the best-score display, and the score storage are all driven by the same local tab, which is why a refresh preserves your best score but a move to another device or a private window resets it. The same control surface is covered in more detail in the keyboard-only walkthrough, which exercises the same Check and scoring flow without a pointer.
A Quick Reference for the Score Flow
- Decide all 25 cells on the fixed 5 by 5 board as either a star or empty.
- Press Check or Enter: incomplete boards report incomplete, invalid complete boards consume one mistake, and a valid complete board awards exactly 1,000 points.
- A second invalid complete check deadlocks the run; choose Restart to play the same board from the original empty state.
- The reward is fixed across visits, devices, and input methods, and it is recreational rather than diagnostic.
