Only the tenant may trigger the clock, and if a visitor arrives whilst the clock is running it will reset, consequently the management advise that the tenant take note of the sending of invites and the arrival of visitors.
If the cycle is completed by someone reaching the 'score target', the next time the clock is activated the Score Target will be incremented upwards.
The management are pleased to inform you that score targets have associated spun 'rewards'. At the time of writing they are as follows:
20 = Spunland Seeds
60 = Spunland Poster 3
120 = Spunland Head (thoughtful)
