Connect Four Spongebob

Play your favourite four-in-a-row game the bikini bottom way!
Drop your counters into the yellow and porous grid and try to make a line upwards, sidewards, or diagonally. Block your opponent with counters - or just use your spongebob blocker to block many holes at once! but look out - if your opponent's counters stack to the top of the grid, they can take away your spongebob blocker!

If you get four counters in a row before your opponent you win!
