Choose the kind of decision you enjoy

Choose PathGlyph if you like testing a hidden route and learning from each attempt. Choose Sudoku for number-placement deduction, a nonogram for revealing a picture from run clues, Flow Free for connecting multiple pairs across a board, or Slitherlink for building a loop from local clues.

This is a guide from the PathGlyph team, not an independent ranking. The useful question is which solving process you want today. The descriptions below use the publishers’ rule pages, checked on October 27, 2026. Prices, availability and app-specific extras can change, so consult the listing of the particular app you choose.

PathGlyph: test a route and keep the confirmed opening

PathGlyph asks you to discover one exact hidden line from S to E. Dot and turn counts constrain it; each checked attempt reveals the correct opening. You draw orthogonal moves without revisiting dots. Matching the counts alone does not prove you found the intended line.

Try it if you enjoy combining a plan with new feedback. You can revise an unconfirmed trace directly on the grid, choose a clue when stuck, and collect solved glyphs. It may be a poor fit if you want unlimited guesses in every mode or want to continue beyond the trial without an account. Campaign lives, ads and online requirements are disclosed in the app listing.

Sudoku: eliminate candidates until a placement is forced

Classic Sudoku uses a 9×9 grid. As the Conceptis rules explain, each row, column and 3×3 box must contain the digits 1–9 once each. You resolve where symbols belong by combining these restrictions.

Choose this style if maintaining possibilities and finding a forced placement is satisfying. Its central action is filling cells rather than drawing a route. If you like Sudoku but want a different interaction, PathGlyph offers movement and feedback in place of candidate digits; it does not try to reproduce Sudoku’s rule system.

Nonograms: turn run clues into a picture

In black-and-white nonograms, row and column clues describe ordered runs of filled squares, with at least one empty square separating neighboring runs. Conceptis calls this format Pic-a-Pix. Color variants have additional rules, so check their instructions separately.

Choose this style if you enjoy switching between row and column evidence and watching a picture emerge. The reward is a completed pattern of filled and empty cells. PathGlyph also leaves a visual result, but you discover an ordered route rather than deciding the state of every picture cell.

Flow Free: connect pairs while sharing space

Big Duck Games describes Flow Free as connecting matching colors with pipes, pairing every color and covering the board. Pipes cannot cross or overlap. Its official page lists Free Play and Time Trial modes.

Choose Flow Free if you like coordinating several connections in the same space. PathGlyph focuses on a single hidden S-to-E route and feedback on its opening. The shared appeal is drawing on a grid; the reasoning differs because PathGlyph is asking you to recover a particular unseen line.

Use a short trial instead of a universal ranking

Try one puzzle in the style that sounds most appealing. Notice whether you enjoy the actual decisions, not just the finished image. Do you want every clue present at the start, or do you like a game revealing information after an attempt? Do you prefer one line, many connections, a picture, or a completed number grid?

Also check the practical fit of the specific product: account requirements, ads, difficulty options, controls and whether a session can be paused. These vary between apps even when the underlying puzzle rules are the same. A satisfying rotation can include more than one format; you do not need to replace a favorite to explore another.
