I took an initial free play of $6 with no rollover requirements from 10 years ago (2008) and turned it into $50 in blackjack. When I tried to withdraw, BetUS.com.pa completely denied me, stating that since I accepted some newer free plays from 2018 (an additional two separate free plays) for $50 each (which lost by the way) the terms of those free plays required a $1k wager and would apply to the entire account, not just those funds. When I asked them to point out where in the terms of service that the newer lost free plays would apply a rollover to the entire account they couldn't. When I asked the associate to escalate the call they lost their cool and terminated my account, and took my funds with it.
Stay far away.
