How to Fix a Connect-Flow Win Firing Before the Board Is Full

Flow free puzzles have two win conditions: all pairs connected and the entire grid filled. Checking only connectivity lets players win with gaps. Add the full-coverage requirement.

How to fix it

1. Verify every pair is connected

For each color, confirm a continuous path links its two endpoints. Walk the path from one endpoint and check it terminates at the matching endpoint.

2. Verify full board coverage

Count occupied cells. The board is only solved when no cell is empty, so the occupied count must equal the total cell count.

3. Require both to win

Trigger the win only when all pairs are connected and the grid is completely filled. Re-check after each path change so partial solutions never count.

Catching the ones you can't reproduce

The hardest version of this to fix is the one you can't reproduce — it only happens on a player's hardware, OS, driver, or save state, under conditions that simply aren't present on your machine. A report that says “it crashed” or “it froze” gives you nothing to act on, so the bug survives release after release while quietly costing you players.

Automatic error capture closes that gap. Each failure arrives with its full stack trace, the device and OS, the build number, and a breadcrumb trail of what the player did right before it broke, so even a failure you have never seen becomes a specific, reproducible issue. Fold identical failures into one signature ranked by how many players each hits, and your worklist sorts itself worst-first instead of arriving as a stream of vague complaints.

This is where a tool like Bugnet earns its place. Its SDK captures every Godot error automatically with the full stack trace plus device, OS, memory, build, and game-state context, folds duplicates into one grouped issue with an occurrence count, and ties each to the build it first appeared on — so you fix the problem that hurts the most players first and confirm it is gone when its signature disappears from the next release.
