Build your first bridge

1. Choose Timber. Drag from a road joint to an empty grid point below the road.
2. Connect that point to another road joint. Repeat triangles, then connect their lower corners.
3. Run test. If a joint folds, add bracing. If a beam overloads, change the material or shape.

Unlocks & medals

Four different clears in one region open the next. Four total clears earn steel; twelve earn cable. Gold needs no hints, target cost and under 85% peak. Silver needs no hints and under 90% budget. Bronze is any successful bridge. Sandbox tests do not unlock content.

Tools

Drawing over an existing member changes its material. Move adjusts a free joint. Erase taps a member. Undo/Redo restore edits. Fixed amber joints attach to the ground. Harbour plans must leave clearance below the road.

Saved bridges & replay

Save names a design. The folder opens, shares or deletes a saved copy. Share exports PNG and JSON; file import is not included. Test ledger stores the last 100 attempts and replays actual recorded motion. Replays do not award progress.

Sound and progress

Workshop has music, action sound, haptic and load colour switches. Deleting local progress requires confirmation. Records stay on this device; no cross-device sync or online ranking is included.

Purchase

Paid once at the store's displayed local price. No ads or in-app purchases. Availability will be shown on the company page after release. This is an arcade game, not professional bridge design software.
