Red cancels green, orange cancels blue, and yellow cancels purple. That bit of color-wheel trivia is the entire rulebook behind Complements unblocked, a physics puzzle by Frank Force built with his LittleJS engine.
Gems roll, bump and settle in a tall well like marbles in a jar. Matching colors cling together, and the second a cluster touches its opposite, the whole group breaks apart. Your goal is to empty the well before the pile gets too high.
How to play Complements
Pick PLAY and a difficulty. EASY starts the well with 20 gems, MEDIUM with 40, HARD with 60 and INSANE with 80. A launcher at the top fires the next gem, and a dotted guide shows its path.
Hold to charge. The loaded gem swells and shrinks while you hold, and it fires at whatever size it has when you let go. Large gems shove the pile around, while small ones slip into tight gaps.
Besides the six colors, watch for special gems. Clear ones pick up the color they touch, white ones break whatever they hit, and black ones only go when a break reaches them. Breaking gems also charges a shake that jolts the pile. A line at the top keeps creeping down, and a gem left above it too long ends the run.

| Grow and fire a gem | Hold Space or Down arrow, release to fire | Hold the left button, release to fire | Hold, then lift your finger |
| Shake the pile | Up arrow or W | Right click | — |
| Pause | Esc | — | — |
Tips
- Grow a cluster, then pop it. Let several gems of one color bond first. One contact with the opposite color then clears all of them together.
- Release early for small shots. Timing the release on the shrinking part of the pulse gives you a small gem that fits where a big one bounces off.
- Spend clear gems on the biggest groups. A clear gem that joins a large cluster can bridge it to its opposite in a single shot.
- Shake to flatten tall stacks. When gems pile up near the line, a shake spreads them out and lowers the height.
- Use the keyboard for fine aim. With MOUSE AIM switched off in OPTIONS, the arrow keys turn the launcher in small, steady steps.
Complements questions
Is there a score in Complements?
No points are counted. Clearing the well records your time, and the best time for each difficulty shows next to its name in the difficulty menu.
I forgot which colors are opposites. Where can I check?
Open ABOUT from the main menu and you will find every pair listed. Black and white also form a special pair of their own.
Can I play Complements on a phone?
Mostly. You can aim by dragging and fire by lifting your finger, but the shake is only on right click or the keyboard, so a computer gives you the full set of controls.
