Color Killer: Don't Blink!

Seven colors fall. You have one thumb and a rainbow bar.

Color Killer is a reaction game built on a single decision, made fast. An orb is falling. It has a color. Tap that color on the bar and a wave goes up to meet it. Tap the wrong one and the wave sails straight past.

That is the whole game. Everything after this is pressure.

THE STREAK IS THE SCORE Every clean hit multiplies the one before it. Two in a row doubles, four quadruples, and past eight the multiplier keeps climbing with no ceiling — a long streak can be worth more than everything you scored before it. Fire at a color that is nowhere on the board and you lose the lot.

CHASE THE RAINBOW One hundred and twenty clean kills charge the rainbow, in three runs of twenty, forty and sixty. For ten seconds every shot destroys every orb, whatever color it is, and your multiplier doubles on top of the streak you are already holding. Ten seconds is not long. Make them count.

SOME ORBS DON'T PLAY FAIR Not everything goes down to one clean hit, and not everything falls straight. Half the game is reading what is coming at you before it reaches the bottom.

IT ONLY GETS HARDER You start with a few colors and earn the rest. Then the game stops holding back and keeps building — faster, thicker — until something gets past you.

SIXTY SECONDS, ONE BOARD, EVERYONE The daily challenge hands the whole world the same board for one day, rolling over at midnight UTC. Sixty seconds. Survive all of them to be ranked: go down early and the run still counts for your own streak, but not for the board.

PLAYS WITHOUT COLOR Turn on color symbols and every color carries a shape as well — flame, drop, leaf, star, moon, bolt, diamond — on the orb and on the key you press for it. The two pairs hardest to separate by hue get the most different shapes.

ONE HAND, NO ACCOUNT Portrait, one thumb, built for iPhone. There is no sign-up, no profile and no server. Your scores, streaks and settings live on your phone and nowhere else. Game Center handles the two leaderboards and the twenty achievements, and only if you are signed in to it.

Seven languages. Sound, music and haptics each have their own switch.
