678KKFlow

678KKFlow is a route puzzle game about covering every edge of a network in a single continuous run.

Play through a built-in campaign of 90 handcrafted levels. Early stages let you start from any node, later stages lock the start point, then add ordered marker nodes, and finally introduce one-way edges.

Each level is designed for short sessions. Drag through connected nodes, follow the available route, and avoid reusing the same edge twice. When you need help, use a start suggestion or a next-step hint based on the remaining exits and direction rules.

The game keeps a local continue state, clear progress, and best results on the device. After a failed run, review the blocking node and decide whether to undo, restart, or try another route.

Included features:

- 90 built-in levels across four rule sets
- Daily challenge from the local level pool
- Continue play for unfinished runs
- Level select organized by chapter
- Settings for snap assist, trail glow, sound, motion, theme, and helper arrows
- Guide, privacy, and achievements screens
- Clear result and failure review screens with local best tracking

The game works offline and does not require an account.
