Spider Linetris

This game combines rules of Spider Line4 and Linetris. It means that pieces can be placed along all four edges of game board (see rules of Spider Line4 for details) and when a base line (first row, last row, top-left column or top-right column) is fully filled with pieces, the line disappears and the rest of the board is shifted to the corresponding side. Similar to Linetris rules, if such filling move is a winning move (connects four or more pieces of the same colour), no disappearing happens and the game is over.
An interesting situation can occur when a player fills two base lines in one move at once. In such case both base lines disappear and the board is shifted diagonally. The following pictures show a position of white placing a piece to H1 square and making the board shift diagonally in down-right direction (before and after the move):
