Play Prism Catch online
Prism Catch is an original color-matching arcade game: a prism paddle slides under a rain of ruby, sapphire, and emerald gems, and only a color-matched catch scores.
Ruby gems score 10, sapphire 20, and emerald 30. Quick successive matches build a combo bonus of up to +25, so a hot streak can carry you to the 800-point target fast — but one greedy grab with the wrong color costs a life.
You have 5 lives and 90 seconds. Gems fall faster as the clock runs down, and switching colors at the last second is where runs are won or lost. Your best score is saved in your browser.

Tips for a better run
Watch the highest gem, not the paddle — early reads let you glide instead of dashing.
Let a wrong-color gem fall: a miss costs nothing, a mismatch costs a life.
Switch color late, not early: set the color when the next gem is close to the paddle line.
Chain matches inside the 1.5-second combo window; the bonus tops out at +25 per catch.
Late in the run, gems fall faster — stay near the middle so both sides are reachable.
Frequently asked questions
How do I move the paddle?
Move with the Left/Right arrow keys, A/D, the mouse, or by dragging on a touch screen. The paddle follows your pointer horizontally.
How do I change the paddle color?
Press 1 for ruby, 2 for sapphire, 3 for emerald, Space to cycle through the colors, or tap one of the color buttons under the game.
How does scoring work?
Ruby gems are 10 points, sapphire 20, and emerald 30. Matching catches within 1.5 seconds of the previous match build a combo bonus of up to +25 per catch.
What happens if I catch the wrong color?
Catching a gem while the paddle shows a different color costs one of your 5 lives and resets your combo. Missing a gem costs nothing, so let a wrong-color gem fall rather than risk a life.
How do I win or lose?
Reach 800 points within 90 seconds to win. Losing all 5 lives, or running out of time below 800 points, ends the run.
