My friend and I just worked on learning this game today. The strategy is quite complex!
Allow redo/restart turn means that you're allowed to change your mind about how to place your dice during your turn. You can "re-do/re-start" as many times as you want until you click 'Confirm'.
I found information about the other setup options by clicking the down arrow and expanding the menus when creating a table.
*Dicey Tomato Rules - Additional points for matching the score value to the score slot number starting with 5 additional points for score slot 1 and decreasing by 1 for each following score slot.
Game end bonus points: 1 for each 2 unused karma, 1 for each 3 red tomatoes still on vines.
*Karma Overload - Karma earned by completing opponent's tomato is equal their score value. 1 karma is earned each time a player gifts 3 dice to opponents. This is being tracked by a Karma bit counter on the player's panel. Maximum Karma is still 6.
*Sunny Gold Hybrid - Additional gold dice used to raise the value of the vine or to counter the effects of the black dice. Same placement rules as for the black dice - cannot be used as seed dice. Can cause overripe - score above 6 are cleared the same way scores below 1 are cleared.
I hope this helps!
