Hexologic asks you to make line totals agree across a hexagonal board. Start with the most constrained line, then use its values to narrow the lines that cross it. You do not need a picture of a completed level to make progress.
Read the arrow and its entire line
In ordinary editable cells, place one, two or three dots. Each arrow-marked line must total the number shown at its edge. MythicOwl explains those values in this developer interview, while its Steam description confirms that sums run in three directions.
Trace the line from the clue before changing a cell. A central hex can affect more than the total you are currently considering. The resemblance to Sudoku is an introduction, not permission to import Sudoku’s rule that each digit must appear only once.
Use minimum and maximum totals first
For a line of ordinary one-to-three cells, count how many are still unresolved. Two such cells can contribute between two and six dots. If their remaining target is two, both must be one; if it is six, both must be three.
More generally, n ordinary unresolved cells contribute at least n and at most 3n. Subtract any already-known values from the target before applying that range. Do not apply it blindly to a later mechanic with different cell behavior.
Carry a deduction into crossing lines
When a cell becomes certain, recalculate the other clued lines that contain it. Suppose an illustrative three-cell line totals seven and two confirmed cells contribute three and two. The remaining ordinary cell must contribute two. Now use that two in its other line.
Keep a distinction between a forced value and a guess. If several assignments still fit, leave the uncertainty in your notes and inspect a different intersection. Changing many uncertain cells at once makes it harder to find the assumption that caused a contradiction.
Learn new mechanics before increasing the challenge
The developer describes different worlds introducing their own mechanics. When a new cell type appears, first observe what can be edited and whether changing one location affects another. Reuse the sum method only after understanding that added constraint.
For practice beyond the authored puzzles, MythicOwl’s Steam announcement explains Infinite Mode: completing a biome’s levels reveals an infinity tile for additional puzzles. Treat it as further practice, not a reason to rush through rules you do not understand.
