Table 4. Design guidelines for social exertion games (Mueller, Gibbs & Vetere, 2009).

	Theme	Design implications
1	Exertion and meaning	Networked exertion games should support meaning making through exertion by supporting various levels of intensity of the game activity.
2	Metagaming	Metagaming is a social play phenomenon that refers to the relationship of a game to elements outside of the game and can be supported by allowing distributed participants to retell the exertion activity with their body.
3	Synchronized exertion	To facilitate the synchronicity between players, offer opportunities for kinesthetic movements.
4	Uncertainty	Exertion can amplify the level of uncertainty afforded by tangible objects.
5	Breaking the rules	Players might reshape the game structure with their actions, with positive and negative consequences.
6	Awareness and exertion	A mismatch of awareness space and exertion space can influence social play. The exertion space might be larger than the game-play, as players move around during and in-between games.
