Play a Neighborhood Hidden-Grid Search Game on Paper

A sheet of paper can hold a surprisingly absorbing search mission. Hide a few shapes, call out coordinates, and use each answer to choose your next square. This small-board game gives nearby adults something to puzzle over together, with no special equipment or speed round to survive.

Choose a table and make matching grids

Ask another adult to try a paper search game at a comfortable table. Agree on a meeting time and a finish time, and check permission to use the space. If you are choosing a nearby meeting place, browse the area guides for context where a guide is available, then confirm access and any cost directly.

Each player needs a pencil and a sheet with two grids. For this version, make every grid six squares across and six down. Label columns A through F and rows one through six, with A1 at the top left. Make the squares roomy enough for clear marks.

Label one grid “My targets” and the other “My searches.” Stand a book between players or angle the sheets so neither person can see the other's layout.

Place the hidden shapes before play starts

Each person secretly marks the same collection of targets on their target grid:

• A straight group occupying three connected squares.
• A straight group occupying two connected squares.
• A separate target occupying a single square.

The longer groups run across a row or down a column, with no bends or gaps. Different groups cannot touch along an edge or at a corner. Every target must fit completely inside the grid. Leave the search grid blank.

For a legal practice layout, put the long group at A1, B1, and C1; the pair at E4 and E5; and the separate target at B6. Check the spaces between the groups together. Use a fresh secret arrangement for the actual game.

Targets stay fixed after the first guess. Both players have six occupied squares to find, regardless of how they arrange the shapes.

Write down the turn and the finish

Choose a starting player. Use these house rules throughout the game:

1. The active player names a coordinate they have not searched before.
2. The opponent repeats it and answers “hit” if it contains a target, or “miss” if it is empty.
3. Both people record the answer: the caller on their search grid, the opponent on their target grid. Use H for hit and M for miss.
4. When every square of a target group has been hit, its owner says “group complete” and names its length.
5. Pass the turn after every guess, including a hit.

Check for a winner after each pair of turns, so both people have made the same number of guesses. If just one player has found all six target squares, they win. If both have, the game is a draw. Keep layouts hidden until both turns in that final pair are complete.

Rehearse a search with the layout visible

Use the practice layout before anyone competes. Call D2. It is empty, so the target owner answers “D2, miss.” Mark M at D2 on the caller's search grid and the owner's target grid. Checking both marks now can save a later conversation about whether the pencil has betrayed you.

Next, call E4. That earns a hit, but the pair is not complete because E5 remains unsearched. In a real game the caller would pass the turn. On a later turn, E5 earns another hit and “group complete, length two.”

Explain that the owner gives no direction hints or information about neighboring squares. A hit at E4 does not tell the caller where its partner lies. Swap roles for another open example, then begin with fresh hidden layouts.

Use the shape rules to choose a search

Early searches give you information about different parts of the board. After a hit, consider the squares directly above, below, left, and right of it. A longer target could continue in those directions. Diagonal squares cannot continue that same straight group.

For example, a hit at B3 might belong to a horizontal group extending toward A3 or C3, or a vertical group extending toward B2 or B4. Unless the owner announces completion, keep investigating. A miss on one side does not rule out an extension on the other.

When a group is complete, you can rule out untouched squares bordering it, including the corners, because different groups cannot touch. Mark those deductions with a slash. Keep M for an actual miss, so you can distinguish answers from your own reasoning. Leave neighboring squares open around an incomplete group.

Keep the records clear and share the thinking

Say coordinates slowly and repeat them before answering. Use large letters or agreed symbols if small writing is difficult. A player can dictate marks to someone they trust; keep each side's hidden information private. With more people, form teams and rotate who chooses the next search.

Invite questions before strategy advice. Our guide to joining a game table as a beginner offers prompts for getting a useful demonstration. Give each person room to choose their own search once they understand a turn.

If the records disagree, pause and check the disputed coordinate privately against the target layout. Correct both records and any deductions affected by the error. If a repeated guess slips through, choose an unsearched square for that turn. When the sequence cannot be reconstructed, agree to restart rather than guessing which account is right.

Reveal the layouts and leave time for a rematch

At the finish, reveal both target grids and check the hits together. Ask which answer changed someone's plan. Comparing the search paths can be as interesting as naming the winner, especially when a quiet corner hid the last target.

For a rematch, make fresh layouts and switch who starts. Keep the same rules until everyone is comfortable. If you reach your agreed leaving time before finishing, call the game unfinished; nobody needs to search every square before catching their transport.

This week, draw the grids, rehearse the E4 example, and offer a neighbor a game. Bring spare paper. Once a person starts explaining their extremely reasonable theory about column C, another blank board may be welcome.
