Opaline Rush

An iridescent orb and a golden gate give you a small upward journey to focus on. The title screen frames it in a bright underwater world, with blue towers, coral, and streams of bubbles. This arcade game keeps the central action simple: each tap sends your orb upward, and your timing carries you toward the goal.

Keep tapping, watch your rise, and find a rhythm that brings you to the golden gate. There are 36 trials to work through, with a gate to aim for as you go. Take a breath between attempts, then try your timing again. You can play instantly in your phone browser.
