A Binero grid never requires guessing: every cell can be deduced, and a steady method avoids failed checks, which are costly for your score. Updated October 27, 2026 [Play Binero](https://play.dev.siwa.io/game/binero) ## Patterns to spot first These three techniques fill a good part of the weekday grid on their own. Sweep every row, then every column, applying them each time. ### 1. Pairs Two identical symbols side by side force the opposite symbol on both ends. In `· ○ ○ ·`, both empty cells take a ●. It is the most common deduction in the game, and each new pair you create often triggers another. ### 2. Gaps When an empty cell sits between two identical symbols, it takes the other one. In `● · ●`, the middle cell must be a ○. Gaps are less visible than pairs, so hunt for them actively, especially in columns. ### 3. Counting On the daily 8×8 grid, every row and column holds exactly four ○ and four ●. As soon as one symbol reaches four, every remaining empty cell takes the other. On the 6×6 easy grid, the threshold is three. ## Techniques for the Sunday grid On Sundays the grid reveals only 18 of its 64 cells, against 26 on weekdays. The basic patterns run out sooner, and these three techniques take over. ### 4. The last symbol When a row needs only one more copy of a symbol, try it mentally in each empty cell. Most positions create three identical symbols in a row and rule themselves out. Example: `● · · · · ○ ● ●`. The row already has three ● and a single ○, so it needs one ● and three ○. Placed 2nd, 3rd or 5th, the ● would leave at least three ○ in a row. It can only go 4th: `● ○ ○ ● ○ ○ ● ●`. ### 5. Unique rows No two rows may be identical, and no two columns. This rule mostly matters late in the game, when a row has two empty cells left, one ○ and one ● to place, and its other cells copy a row that is already complete. Example: row A is complete, `○ ● ● ○ ○ ● ○ ●`. Row B reads `○ ● ● ○ ○ ● · ·`. Placing ○ then ● would make it identical to A, so the order must be reversed: `○ ● ● ○ ○ ● ● ○`. ### 6. Back and forth between rows and columns Each symbol placed in a row changes the column that crosses it. After every deduction, look straight away at the column of the cell you just filled: that is where the next deduction usually hides. Cells sharing the selected cell's row and column are highlighted, which helps you keep track. ## Managing the endgame ### 7. Review before the last cell Binero only judges the grid once it is full. As long as one cell is empty, you can change, test and undo with no penalty at all. Every full grid judged wrong, however, removes 10% of the performance score, with no floor. Before filling the last cell, run a quick check: - no run of three identical symbols, in rows or columns; - four ○ and four ● everywhere; - no two identical rows or columns. ## Using notes and hypotheses Notes mode lets you mark ○, ● or both in an empty cell without filling it. Use it to keep track of a partial deduction, such as "this cell can't be ○ if its neighbour is". For a longer hypothesis, you can also fill cells directly as a draft: as long as the grid is not full, nothing is checked. If the hypothesis leads to a contradiction (three in a row, five ○ in a line), step back with the undo button, labelled Annuler: the starting cell takes the other symbol. Save this method for genuinely stuck positions, as direct deduction is faster. ## Score and timer The score out of 1000 combines performance, jokers and time. The reference time is 4 minutes on weekdays and 6 minutes on Sundays: finishing twice as fast earns the maximum 20% bonus, while a very long game gets a penalty capped at 25%. You can collapse the timer with a tap if the numbers distract you, but it keeps running. To review the basics, read [how to play Binero](https://dev.siwa.io/en/guides/comment-jouer-a-binero).

Where should you start a Binero grid? Start with pairs (two identical symbols side by side) and gaps (an empty cell between two identical symbols). Both patterns are easy to spot and often unlock a third of the grid.
What should you do when a Binero grid seems stuck? Count the symbols in each row and column, then look for lines missing only one copy of a symbol: most of its possible spots would create three identical symbols in a row. If nothing moves, compare nearly full rows with finished ones.
How much does a failed check cost in Binero? Each full grid judged wrong removes 10% of the performance score, or 100 points out of 1000 before the difficulty multiplier. There is no floor: after ten failed checks, only speed still earns points.
Is it better to use a joker or hunt for the error yourself? A joker costs about 60 points, less than a failed check. On a full but wrong grid, the joker reveals one of the wrong cells, which is safer than flipping cells at random.
