How do I open a Safe and collect the Ruby?

Only power-ups can open a Safe. Matches next to it have no effect.

Use a power-up whose blast reaches the Safe. A Safe may need more than one hit. Keep hitting it until it breaks; the Ruby inside is then collected automatically.

Reaching the Safe

A Bomb can hit a Safe within its blast area. If you can’t create a power-up close enough, a Bomb + Rocket combination blasts three rows and three columns, which may let you reach the Safe from farther away.
