Autoreset should let the current game play out, or at minimum the current ball. It's sad to see the ball being played in a good round, then the 2x zones disappear and the ball falls because the autoreset happened.
With last night's update, if you have it set to auto reset for 75 shares and you buy a Double Shares upgrade, it will automatically change it to auto reset for 150 shares, when you prestige for mana and lose that multiplier it will revert it back to 75. You can turn off those adjustments by pressing the lock check box under the amount.
It would be nice to know how many more levels until max. I'm sitting here maxing everything and I have a couple in each world that don't seem to have a max.
The prestige screen numbers seem to be stuck at 184/s for the first "world" and 222/s for the second, despite me upgrading things significantly in both.
I'm not sure how the buttons are related to the different signs, as I couldn't see any answers, so I ended up finding the answers, then brute forcing them anyhow.
There are two solutions to level 15 due to both "white squares only" columns at the top being a difference of three, meaning that you can flip both columns and be right. Without giving away too much, the "correct" answer is with 2 on the top of its column. You should be calculating a win state not by proper placement of the cards, but by fulfilling all of the qualifications of the rules. Then even if your design allows for multiple solutions they would pass.
