A car slides at speed across a frozen road with almost no grip. Tap left or right to steer around crumbling ice patches, oil slicks, and snowdrifts that appear with no warning. Rare speed boosts launch you at triple speed for a thrilling moment. Slide off the road and the car spins into a snowbank.

Hold and drag to steer a lone spaceship through an ever-denser field of drifting asteroids and energy barriers. Stars collected along the route charge your boost meter — release to burst through tight gaps. The asteroid field rotates slowly, constantly changing which gaps are open and which are closing.

Enemy waves march down three lanes toward your fortress and you tap each lane to launch fireballs. Armoured enemies take two hits, shield enemies block the first fireball, and ghost enemies phase through fire — you need ice blasts for those. Survive thirty waves to ignite a bonus inferno round.
