Thanks for your comments. This was my first challenge and it's been very good. There seems to be a lot of questions, so I'll try to explain my thinking as much as possible.
Firstly, it was meant to be a very simple game without a lot of strategy but, obviously, this can put some people off.
Generally, I like to be much more thematic and illustrative in my rules but the word limit and lack of images was a shock for my first challenge.
Clarifications
Thank you Mr S. No, it's not that abstract. That was left in from when the game was originally more abstract. I don't want to get into definition discussions but... chess.
I do realise I should have been clearer:
should have been "...any of their own pieces, which have not been attracted towards the centre,..." (pieces which are attracted cannot be moved by the player in that turn, other than being attracted to the centre one space)
Players also can't move their pieces away from the centre (expect for the spaces that allow it).
The spaces nearer the centre would be have the greater point gains and losses.
The only time a player might move another players pieces would be by landing on the space that allowed it but this was really just a filler action, so I'll remove it.
An invalid spin is if the pointer of the spinner fails to rotate enough to move past two whole spaces. This was to get a balance between avoiding players just tapping the spinner slightly to not hit their own piece and to allow a player to still spin it softly. However, this whole idea could just be removed and say that the spinner has to spin completely...
Comments
The idea of hitting the pieces away with the spinner was what gave me the space theme because of the many sci-fi ideas of black holes, like 'teleporting'.
I could have the game in the box to avoid lost pieces but with a specific "out of play" zone, to avoid every piece staying on the board, but I don't think it would be too much of an issue in practice.
I really like anonymousmagic's idea of a modular board. Perhaps I could have different quarter-circles that fit together to make a circle and each one would have a different arrangement of spaces instead of just concentric circles. This would give more strategy to where you moved your pieces.
I'll do more proof reading next time :)
Thanks.
