Lock casino using games from real time gaming software, but i had much more experience in lock poker, not in lock casino. By the way i played poker and casino at lock site about 4 years ago, and since i read almost all poker forum sometimes (just visit few times in a week to read some news), i can say that nowadays lock casino and poker in big trouble, and most players have trouble with receiving their money, so i suggest you to stay away from this casino, it is not very good anymore.
I played at lock casino like i said only once, and it was when i was super angry when losing tournament with 30$ buy-in, i had aces, and go all-in, it was already final table, and some idiot call my all-in with A2, of course he get straight from A to 5. Moron, nothing else. At casino i deposited 30$ and take 100% bonus, i was angry and really want only win some money, win it fast, to recover my potential winnings in poker tournament. Unfortunately i was a dumb and of course i was in tilt, so with 60$ balance i open first game that i think can pay good, it was paydirt, and i start playing with 1$ bets, which is of course big mistake and such ultra high variance game like paydirt. At least i have few features, but they pay bad, and just make me more angry about it. After about 20 minutes of playing i lost my deposit and bonus. So you should know that when you angry about anything, start gambling it is really not best idea, because gambling should give only fun, no angry thoughts.
I rate lock casino with 3 stars, because right now this guys sent withdrawals very rare, and in most cases you did not get any of your winnings, i say this based on many players posts, so be careful.
