Smash Grid is a 1v1 disc battle game. You and your opponent each defend a wall of blocks. Drag to aim, let go to throw, and smash their blocks before they smash yours. When their disc comes flying back at you, catch it before it lands. A match takes a couple of minutes. It's easy to pick up and surprisingly hard to get good at, because the best shots come from reading where your opponent is and finding the gap. PLAY ONLINE Get matched with a real player in seconds and battle it out in real time. It's straightforward 1v1 PvP: your aim against theirs. CHALLENGE YOUR FRIENDS Invite a friend and play a 2 player match head to head. Anyone who joins with your invite code gets bonus cash to start with. CONQUER SOLO LEVELS Play through quick matches to work your way upto interesting levels filled with new obstacles and power ups. SIX ARENAS, RISING STAKES Every online match is played for in-game cash. Win and you take your opponent's stake. Lose and it's theirs. Start in Rookie Circuit for 100, then work up through Amateur Open, Pro Division, Alpha Sector and Master League to Titan Grid, the biggest stake. EARN TROPHIES Wins earn trophies. Losses earn nothing. Your trophy count shows how good you actually are, whatever your cash balance says. Note: In-game cash is for play only. It has no real-world value and can't be withdrawn or exchanged. We're a small team and we read every review. If something feels off, tell us there.
