Every round, three moves

Each round opens with a short planning phase. Then your defenders take over.

  1. Buy from your hand

    You're dealt three cards. Spend gold on the ones you want, freeze one to keep it for later, or refresh the hand.

  2. Merge two of a kind

    Drop a defender on its twin. One star becomes two, two become three, and its damage doubles each time.

  3. Hold the star

    Defenders fire on their own. Every enemy that gets through knocks hearts off your star. Clear the round to earn more gold.

Four Ember Foxes and two Arc Owls. Find the pairs.

Three ways to play

Every mode uses the same deck and the same rules, so everything you learn carries over.

Solo

100levels

Dungeon

Fight through the levels one at a time. A boss waits at the end of every level, and each one hits harder.

1 vs 1

7leagues

Arena

Face a live opponent. Every defender you place also sends enemies down their lane. Win trophies and climb from Stone to Champion.

2 players

5worlds

Co-op

Team up with a friend, share one star and beat boss runs across five worlds, from Rookie all the way to Nightmare.

30 defenders. Pick your eight.

Every defender has its own trick: burn, freeze, chain lightning, bank gold, heal the star. The best decks make them work together.

Five worlds, five crowds

Each co-op world sends its own enemies and ends every run with its own boss. Beat the fifth run to open the next world.

Crabs, mudskippers and hermit crabs storm the piers. A colossal crab closes every run.

Boss

Every run comes in five difficulties, from Rookie to Nightmare. Clear Nightmare and Endless opens up.

Your deck keeps growing

Win packs, open them for card parts and level up your favourites. The more you play, the stronger your eight.

  • Level cards to 30

    Every level adds 5% attack. Levels 10, 20 and 30 also power up the card's ability.

  • Unlock Evolutions

    Rare pack pulls unlock new forms, three for every defender. There are 90 to find.

  • Climb the season pass

    100 levels of rewards. Every level pays a free reward, and Premium adds a richer one at every level.

  • Walk the trophy road

    Arena wins move you through seven leagues, with a reward every 50 trophies.

Fair by design. Packs come from the daily reward, every 10th Dungeon level, completed Co-op sets, the trophy road and passes, or the shop. Diamonds are optional and never enter a match.

Questions

Straight answers about modes, co-op, devices and what's free.

Is Starvoxel: Defender free?

Yes. It's free on the App Store and Google Play, with no ads. Diamonds and the Premium season pass are optional purchases.

Can I play on my own?

Yes. The Dungeon is 100 levels of solo play. In Arena and Co-op, if nobody is found within ten seconds, an AI player takes the empty seat.

How does co-op work?

You and your partner each bring an eight-card deck, build on your own 3x3 board, and defend one shared star. Invite a friend by username or get matched with another player.

How does an Arena match work?

Both players plan for 30 seconds, then the round plays out. Your defenders send enemies down your opponent's lane, and the first player whose star runs out of hearts loses.

Which devices and languages are supported?

iPhone, iPad and Android phones and tablets. The game speaks 22 languages, including Spanish, Portuguese, German, French, Japanese, Korean, Chinese, Arabic and Turkish.

Will my progress move to a new phone?

Yes. Your cards, decks and progress live on your account. Sign in with Game Center or Google Play Games to pick up where you left off.
