In sudoku battle, you are showing including the nos. of robots in the "players online" displayed on main page.
Some of us would like to play with humans, not with robots, so when we see 6 players online, we go all the way to the page, see the compulsory ad, click 2-3 starts, online to find that all online are robots that we don't want to play with.
so my suggestion is, to remove no. of robots from "players online". Show only human players count, or separately show humans and robots online.
