Bubble Rainbow — free browser game

Bubble Rainbow is a colour-order reaction game. Bubbles of seven rainbow colours (red, orange, yellow, green, blue, indigo, violet) rise from the bottom of the tube and eventually escape through the top edge. The 'Next' panel just below the HUD shows the colour you have to pop right now as a big dot. Your only job: find a bubble of that colour on screen and tap it. A correct pop scores +1 and the required colour advances by one step — red → orange → yellow → … → violet → back to red. Tap the wrong colour and you lose one of your 3 lives. Bubbles that drift off the top without being touched are neutral; they just disappear, no penalty. The bubbles wobble sideways a bit so aiming asks for some persistence; the nearest bubble centre to your tap is the one that pops. Every 7 correct pops (one full rainbow round) the level steps up: bubbles rise faster, spawn more often, and crowd the tube more. When all 3 lives are gone the run ends and your best score is saved locally. Tip: look at the bottom of the tube first — those bubbles are youngest, easiest to read at a glance, and you have the most time to act on them. R always resets; Space/Enter mirror the Start and Restart overlay buttons.
