Unlocking builders 5 & 6
Master Builder, B.O.B, and when your timeline assumes extra builder slots.
Home village builder count affects how fast the forward timeline finishes. ClashCookie infers your slots from Town Hall level when you haven’t imported active timers.
Builder milestones
TH4: 2 builders · TH6: 3 · TH9: 4 · TH14: 5 builders (plus Master Builder from Builder Base).
B.O.B (6th builder) unlocks from Builder Base progression - timeline uses 6 slots at TH14+ when applicable.
TH range calculator
The How long to max (TH range) tool estimates parallel build time from your TH-based builder count and shows gem cost for 1 builder vs all builders.
Personal timeline is more accurate once you import - it respects your real queues and active upgrades.
