🔤 About WordFlow

WordFlow is RivalPit's word-puzzle spin on InkFlow: instead of numbered checkpoints, every checkpoint carries a letter, and reading them in order spells a hidden word. Every puzzle is solvable by construction -- there's always at least one valid path -- but finding it is the whole game.

Boards start small at a 5x5 grid spelling a 4-letter word, and grow as you clear levels: the grid gains a column roughly every 3 levels up to an 8x8 cap, and the hidden word gains a letter roughly every 4 levels up to 8 letters, so the puzzle keeps scaling in both size and word length the further you get. Your level is saved on this device, so you always pick up where you left off.

How to Play

  1. Draw one continuous line through every square on the board -- no square skipped, none visited twice.
  2. Your line has to start at checkpoint 1 and end at the last checkpoint, hitting every checkpoint in between in order.
  3. The letters on the checkpoints, read in order, spell a real word once you finish.
  4. Every checkpoint sits on a fixed, valid Hamiltonian path through the whole grid, so a solution always exists -- if you're stuck, the puzzle is solvable, you just haven't found the route yet.
  5. Tap or drag back along your own line to undo part of it if you paint yourself into a corner.

Levels are endless and randomly generated, starting small and growing tougher -- bigger grids, longer words, no hints, ever.

Work backward from the later checkpoints as well as forward from checkpoint 1 -- since every square must be filled exactly once, ruling out routes near the end of the path narrows your options at the start too.

Frequently Asked Questions

Is WordFlow free to play?

Yes. WordFlow is completely free to play in your browser at rivalpit.com/wordflow/, no download, install, or account required to start playing.

How do you play WordFlow?

Draw one continuous line through every square on the board, starting at checkpoint 1 and ending at the final checkpoint, visiting every numbered checkpoint in order along the way. The letters at the checkpoints, read in order, spell a hidden word.

Does WordFlow have hints?

No. WordFlow is designed to be genuinely hard, with no hint button -- every puzzle is solvable by construction, but you have to find the path yourself.

Are there a limited number of levels?

No. Levels are endless and randomly generated, starting on a small grid with a short word and growing into bigger grids with longer hidden words the further you get.

How big do the grids and words get?

Grids start at 5x5 with a 4-letter word and scale up as you progress -- the grid grows roughly every 3 levels up to an 8x8 cap, and the hidden word grows roughly every 4 levels up to 8 letters long.

Does WordFlow save my progress?

Yes. Your current level is saved automatically on this device, so closing the tab and coming back later picks up right where you left off.
