Hi HDChung, thanks for the better 14L, it looks much better with the 100% chance and all the extra t-spin / tetris chances. Just wondering, how often is the first solution possible? I've tried it about 20 times and I've always been able to use the first solution. Thanks. -10Penta

Just checked, 83.45% [4206/5040 bags] without 180, 93.93% [4734/5040] using 180 -Ivan28283

Ok, Thanks! -10Penta

WAO IVan pro. Yeah the first solution is very frequently possible as the only dependency is not for S,Z,T to block I,L,J,O below and S or Z to come before T. - HDChung
