Space Diamond Miner is a free online puzzle arcade game where you control an astronaut swinging a hook to grab diamonds buried beneath the surface of alien planets. Inspired by the classic Gold Miner formula, each level gives you a strict time limit to haul in enough diamonds to hit your target score before the clock runs out. Timing your hook release is everything – swing too early or too late and you will miss high-value gems sitting just out of reach.

What keeps Space Diamond Miner addictive is the upgrade system between levels. Diamonds you collect are actual currency you spend on faster hook speed, a bigger hook size, extra seconds on the clock, or boosted diamond values. Prioritizing upgrades matters – grabbing a hook speed upgrade early makes the whole run feel more manageable. The colorful space setting adds a fun twist on the familiar mining mechanic, and the casual difficulty curve means you can make steady progress without grinding.

This game is perfect for fans of classic arcade puzzle games, Gold Miner enthusiasts, and anyone who enjoys casual one-player browser games with simple controls and satisfying progression. Whether you are searching for free space puzzle games, online mining arcade games, or classic hook-and-grab style games to play without downloading, Space Diamond Miner delivers a quick and genuinely fun session every time you load it up.
