im only level 2,
but i try not to look at the seconds, i just look to the top right square. if it is red i bet, if it is yelow or green i dont bed.
if after three rounds there are still a lot of people bidding, i tap out.
Also if i find someone who will bet several tokens per round i will follow several rounds with one bet, if he keeps up the pace he probably has plenty tokens, so i tap out.
if i find someone who tries to bet every last seconds, it probably means they dont want to spend too many tokens(or dont have many tokens), so i stay in. they usualy leave after a few rounds.
Like someone said earlier if you dont have many tokens, dont try to bid on expensive players.
