In <b>Crystal Roller</b>, set on a glittering crystal cavern, you face a roll to goal where a draw-then-release puzzle where you sketch ramps to roll a ball into a goal cup.

If it misses, you tweak the lines and try again — it is a calm, clever marble-run puzzle where one elegant curve can solve the whole thing.</p><p>Your objective: draw ramps that roll the released ball across the level and drop it cleanly into the goal cup. Reading how the ball will pick up speed down a slope is the heart of the puzzle.</p><p>Everything runs offline-friendly in the browser, your best score is saved on your device, and it is completely free.</p><p><b>Crystal Roller</b> plays twitchy and reflex-driven across a glittering crystal cavern — the cave roll to goal curve is gentle at first and genuinely tough at the top.
