This post is dedicated to all who are frustrated with C2’s challenge: Empty House. The goal of the challenge is to clear all pieces from the board.
This challenge is hard because the pieces which you get are completely random. However there is a way to clear this challenge using just 7 pieces. The order of the pieces matters slightly, but what is most important is that you get an even number of T pieces, and go for a 3 line clear or a 2 + 1 or 1 + 2 line clear
Here are some sample solutions:
Of course these are not all the solutions to the problem. Here are some (unlikely) solutions to the problem without T pieces:
There you have it. If get to a situation where you have 1 extra piece, you could try using the Perfect Clear strategy here after clearing the grey blocks. Good luck!
