The main strategy in Gaining Gravity is to balance between caution (don’t be knocked home by your opponents game piece) and greed (capture as much prey as possible).
Keeping up appearances:
Perhaps your opponent is able to knock you out – but he might be more interested in capturing preys. Don’t let him discover that he can knock you out.
Figure it out:
Gaining Gravity is played on a sort of tilt. This means that weight close to the middle of the board will appear to weigh less than weight situated longer away from the middle. It is also a good idea to figure out the probability for being knocked out by your opponent.
If you can place your game piece in the middle of the board – but in safe distance from your opponent – do it. Thus your opponent will have trouble to make a safe move when it is his turn. Find out what kind of risk you want to take to find the balance between capturing prey, stealing space or being knocked out.
