Oware Rule Update - Seed Capture on Repetition

We've made an update to our Oware rules (playstrategy.org/variant/oware) regarding what happens to remaining seeds when the game ends under repetition.

Previously all remaining seeds were shared equally between players, with any remainder going to the player with the most seeds on their side of the board.

Now, each player captures the remaining seeds on their side of the board when the repetition is called.

The definition of repetition in Oware remains unchanged - the game ends as soon as a position is repeated.

All previous games that were run under the old rule will have their results unchanged, although the score shown will be with the new calculation. Going forward this rule alteration brings PlayStrategy into line with the more common ruleset for Oware.

As an example, please see: playstrategy.org/nOnJqb7U#146 With the score at 20-20 a repeated position was detected on ply 147 (same position as ply 125). The previous rules allocated 4 seeds to each player, as there were 8 seeds remaining, and the game was a draw 24-24. With the new rules, South would be allocated 3 seeds and North 5 seeds making North the winner at 23-25.

Finally, we have updated the end game message in Oware games to explicitly state 'Game finished via repetition' when this is the case. We hope this makes these situations a bit clearer.
