What people say


First time using Simlabs and finished 1st in $3 Play Action on DK. Tied for first and won $1318.42. Awesome tool and I enjoyed not having to establish all the rules that I usually do using LineupHQ. Great job RG team!


This seems so easy to use that I feel like I'm doing something wrong
