Gravity TD

Gravity TD (Japanese name... グラビティーTD) is one of the TD Attack Openers and one of the C-Spin Openers. It is very easy to operate when building in the left roof orientation and can be stacked quickly with fewer softdrops. This opener was invented by Deuru.

1st bag
Stack them like this. Setup probability is 70.00% on one side and 88.65% on both sides.

The left roof is easier to operate, so give priority to that as much as possible. In the following explanations, left roof is used.

2nd bag
TST is always possible. There are six ways to stack. The last of these can always be stacked, but avoid them as much as possible because they create voids. The five stacking methods other than the last cover 99.37%.
