Instruct your captain to invent an item, then pause
game play. Set the game speed to full and wait approximately two
minutes. The item will have been invented when game play resumes.
Alternatively, click on the invent option, then click on it again
when your mean leave. This may be used to create an instant catapult,
but may only be done once per island.
Take a single captain to the north section of the map
during winter. Leave him at that location and he will eventually
shear and eat a sheep.
