Red and Green Rainbow
Why We Picked Red and Green Rainbow
Red and Green Rainbow keeps its distance short and its retries free, which is the whole of its generosity. A run ends at the hazard rather than at a menu, and the retry puts you within sight of the mistake. Small in scope, careful in layout, and over well before it overstays. Position 107 of 500 undersells it slightly; the games above are longer, not better made. By the numbers: 4.4 out of 5 from 624 ratings.
How to Play
Three rules cover almost everything this game asks of you:
- Directional keys only, which keeps the hand in one place.
- Get through the route in one piece; the retry is cheaper than the detour.
- Take the obvious path first, then the one that looks like scenery.
Editor’s Note
Better on a keyboard; touch works but the jumps are tighter than they should be. Fullscreen matters more here than on the arcade shelf, since the visible edge of the level is information.

Red and Green Rainbow is a two-character platform adventure in which a red hero and a green hero have to work together to escape trap-filled levels full of slime, bats, lasers, and locked doors. This entry in the long-running red and green series adds more enemies and more mechanics than before, and it is at its best when two friends share a keyboard, though a solo player can switch between both characters and manage the puzzle alone.
Controls are split so each player has their own set: one character moves with the WASD keys while the other uses the arrow keys, and both can double jump, which is essential for reaching high ledges and clearing wide gaps. On mobile, touch controls handle the same moves. Each level asks the pair to grab the key, survive the hazards, and reach the exit together, and the twist is that the two heroes have different jobs. Only the green character can remove the laser barriers, and finding the key makes the invisible door visible, so progress always depends on using both heroes' strengths.
The difficulty builds steadily across the stages. Early levels teach the basics of coordinated movement and key hunting, while later ones layer on moving enemies, tighter jumps off ramps, and sections where one hero must hold a position so the other can pass. Slimes and bats patrol the platforms and a single touch costs you, so timing and communication matter as much as reflexes.
A few habits make the journey smoother. Scout each new level before committing, so you know where the key and the hidden door sit. Send green ahead to clear lasers before moving red into danger, use the double jump to hover past bats rather than racing under them, and remember that jump ramps often hide the fastest route upward.
Red and Green Rainbow is ideal for siblings, friends, and couples who want a cooperative challenge, and it costs nothing to play in your browser, on a shared keyboard or on touchscreens.
