Odd poker tournament set up - all short stacked

[Benoit]

At the nearby card club, they have a quick $10 buy in tournament each morning. They do it on 2 tables with rebuys until the first blind increase, and they increase like every 10 min. The starting amount is $300 in chips and the 1st level being $20/$40. Now it's odd to me, but to call you need 3xSB and to raise at least by 3xSB, so at least $60 pre-flop to call. Last part is they pay the top 3 spots (higher the spot, the larger the payoff), but no heads up play because they stop when only 3 are left and count up their chips for rank.

So anyway for strategy starting out, it seems like my only choice is to go all-in with any good hand and hope to pick up the blinds or double up. If you get lucky enough to build up faster then the blinds, then you can play normally somewhat... Anyway that's my take, what's your take?
