Any chance of giving Gattai-3 on this site?
It is like T-joint (troynik) but with different arrangement.
Thanks.
Let's ask @GrandGames 
Можно ли добавить еще такой вид судоку? Гаттай-3, или тридоку
There are a "T-joint" and a "Triple Sudoku" in the multi-sudoku section currently.
This is a different version. Its placement of overlapping grids is different.
Why would someone ask to add a version that is already existing?
