Prisma Defender

The sky is falling in colour. Every meteor arrives tinted, and your cannon fires whatever light you load into it. Dial in red, green and blue, match the shade exactly, and one shot is enough. Miss the mix and the shot is spent for nothing.

HOW IT PLAYS

Three sliders feed one barrel. A meteor the colour of deep violet needs red and blue in the right measure; a pale one needs all three. Set the mix, aim, fire. A perfect match destroys the meteor and pays half the light back into your tanks. A near miss strips one channel and leaves the rest falling.

Light is finite. Every shot costs from the red, green and blue tanks, and the tanks only refill from clean kills. Waste shots and you run dry with the sky still full. The tension is not your reflexes, it is your accounting.

THE PRISM SURGE

Clean play overflows your tanks, and the overflow charges the Prism Surge. Fire it and the cannon runs on every wavelength at once for a few seconds: no dialling, nothing rejected, everything you touch dies. Tap it again to bank what is left and save those seconds for a wave that needs them.

Let the Surge sit full and the overflow keeps going somewhere better.

THE CARD PICK

Overflow past a full Surge earns a pick. Three cards rise, turn face up so you see what is on offer, turn back down, and shuffle. Choose one and keep it:

- PAUSE freezes the sky for five seconds - SLOW drops every meteor to a third speed - REWIND sends them back up the way they came

Bank enough overflow and the jokers disappear from the deal, until every card on the table is worth having. Hold up to nine and play them when a wave turns.
