Bloxd.io is a free browser voxel game where players build, explore and fight, and its fight chests give players loot after combat encounters. The opening and item drop sounds mark that transition from fighting to reward, which is why clips of them are shared on soundboards by players and editors who want a ready-made game effect without recording gameplay themselves. It remains useful because the sound is short, instantly readable as a prize being collected, and fits Minecraft-style builds, challenge videos and gaming memes.
