Lock N' Roll is a thrilling dice game where strategy meets luck! Grab some dice, gather your friends, and see who can score the highest. HOW TO PLAY Roll two dice on your turn and watch your round score grow. The first 3 rolls of each round offer bonus scoring — rolling a 2 or 12 earns a 200-point jackpot, and 7s are worth 100 points. Doubles multiply your entire round score by 2! But be careful — after your first 3 rolls, rolling a 7 wipes out your round score completely. Lock in your points before it's too late! FEATURES - 2+ players — perfect for game night - Choose 5, 10, 15, or 20 rounds - Special bonus scoring on early rolls - Risk-reward strategy: push your luck or play it safe - Simple to learn, hard to put down - Completely free to play - Whether you're at a party, family gathering, or just hanging out, Lock N' Roll brings the fun.
