Start with a row or column containing two given numbers. Then check the smaller 2×2 boxes before making a guess. This is an easy number puzzle, but it still exercises elimination and concentration.
Visual and Deduction Puzzles: Nonogram and Logic Grid
Nonogram instructions: Shade cells to reveal a five-by-five picture. A number indicates a consecutive run of shaded cells; multiple numbers indicate separate runs in that order, with at least one blank cell between runs. The row clues appear first, followed by the column clues.
Row clues: 2; 3; 1, 1; 3; 1
Column clues: 1; 5; 2, 2; 3; 1
□ □ □ □ □
□ □ □ □ □
□ □ □ □ □
□ □ □ □ □
□ □ □ □ □
Use the row with a clue of 5 first, then compare filled cells against the column clues. This visual format is medium difficulty because a correct mark can unlock several lines at once.
Logic grid instructions: Ava, Ben, and Cara each arrived on a different day and chose a different snack. The days are Monday, Tuesday, and Wednesday. The snacks are almonds, cookies, and fruit. Mark each grid with an X or a check as you solve it.

- Ben arrived on Wednesday.
- The person who chose fruit arrived on Tuesday.
- Ava arrived before the person who chose almonds.
- Cara chose cookies.
- Ava did not arrive on Tuesday.
For this deduction puzzle, place the fixed information first, then test the remaining day and snack combinations. It is medium difficulty: each clue is simple, but the answer depends on combining them rather than using one clue alone.
