How to Solve Logice: Logic-Grid Deduction Step by Step

Logice presents two or three separate logic tables. Each table links the same set of identities in its rows to one category in its columns. Tap a cell to cycle from blank to no to yes. Every row and every column receives exactly one yes, and placing one automatically fills the rest of that row and column with no marks.

The interface does useful bookkeeping, but it cannot decide which clue to use next. The most reliable approach is a deduction loop: translate a clue, place only what it proves, let auto-elimination run, then read the clues again in light of the new grid.

Step 1: Bank the direct facts

Start with clues that state a direct match or exclusion. A direct “is” gives you a yes. A direct “is not” gives you a no. Enter all of those before touching either-or or relational clues.

This first pass is intentionally boring. It creates the foundation for every later chain and reduces the chance that you will hold a fact in memory but forget to use it in another table.

Step 2: Let rows and columns finish themselves

If a row has only one blank left, that cell must be yes. The same is true for a column. Because each category is one-to-one, a confirmed yes also removes that option from every other identity automatically.

Watch the clue tiles as you work. Green means a clue is satisfied. Red means your current marks contradict it. A red clue is not a hint to guess elsewhere; it is a precise signal that one of the marks involved in that clue needs correction.

Step 3: Carry facts between tables

Suppose Alex is matched with Tuesday in one grid, and Tuesday is matched with the red item through another clue. Alex must therefore be associated with red even if no clue says that sentence directly. These cross-table chains are the heart of Logice.

When stuck, choose one identity and read its confirmed matches across every table. Then ask what each remaining clue says about that combined profile. This is more productive than staring at a nearly empty subgrid in isolation.

Step 4: Treat pairs as a unit

Sometimes two identities are restricted to the same two choices. You may not know which pairing is correct yet, but you do know every other identity is excluded from both choices. Mark those outside cells no.

This “locked pair” deduction is valuable because it makes progress without guessing between the two possibilities. A later clue will break the tie.

Step 5: Re-read, do not merely re-scan

A clue that looked weak at the start can become decisive after several matches are known. Read the whole sentence again and substitute the confirmed information. Relational wording often collapses into a direct yes or no once one participant has been identified.

Keep a simple discipline: every time a yes appears, revisit clues that mention either side of that match. That is where the next cascade usually begins.

A short example of the deduction loop

1. A clue rules out two cells in Maya's row.
2. Only one candidate remains, so Maya receives a yes.
3. Auto-elimination clears that column for everyone else.
4. Another identity is now left with one candidate in the same table.
5. That new match turns a previously vague clue into a direct exclusion in the second table.

What to do when two clues seem to disagree

Do not assume the puzzle is asking for a guess. Open the red clue and identify the exact identities and categories it references. Then trace only the yes marks that feed that contradiction. One of them may have been inferred through a chain that included an unsupported assumption.

Remove the earliest unproven yes, not every mark in the grid. The no marks created by direct clues can usually stay. This turns a contradiction into a short audit trail and preserves most of your progress.

That loop is the real skill. You are not trying to solve one clue at a time. You are trying to create a small fact that changes the meaning of several other clues. When every grid is filled correctly, Logice completes automatically, so there is never a reason to force a final guess into the middle of an unfinished table.
