About this game

Spearfin is a swordfish io game in a 3D ocean: steer a real swordfish, spear rival fish from the side with the tip of your sword and grow until you rule the sea. Every round is offline, against 11 computer-controlled (AI) rivals.

HOW A ROUND WORKS
• Drag anywhere to steer. Your fish follows your finger through the water.
• Hit a rival's body with your sword tip to take its mass and grow.
• Sword tip against sword tip is a parry: both fish bounce away.
• A small fish can still wound a big one from the side, so watch your flanks.
• Tap DASH for a burst of speed; the ring on the button refills in seconds.
• When the clock runs out, the heaviest fish wins the round.

SIX REAL SPECIES
• Swordfish: balanced all-rounder.
• Needlefish: tightest turns, short beak.
• Sailfish: fastest fish, longest dash.
• Blue marlin: strongest stab and a tough body.
• Sawfish (Pro): widest strike, hard to dodge.
• Narwhal (Pro): longest tusk, toughest of all.
Each species swims differently. None is simply stronger, so skill decides the round.

THE SEA CHANGES EVERY ROUND
• Bait ball: sardines packed together, feast fast.
• Deep sea: glowing squid rise from the dark and are worth more.
• Night sea, strong currents and a golden bounty on one rival.

MORE TO DO
• Ocean book: meet a species in the sea to read real facts about it, from the narwhal's tooth-tusk to the endangered smalltooth sawfish.
• Daily sea: the same sea for everyone, once a day.
• Records for your biggest size, wins and rivals speared.
• Plays offline. No account, no chat with strangers.

A FAIR SWORD FISH GAME
This fish io game stays inside the game: no launcher, no wallpaper changes and no ads outside the app. Rivals are AI and are marked as AI on the leaderboard. Sizes and powers are game values, not real biology.

SPEARFIN PRO
One payment, no subscription: no pop-up ads, the sawfish and narwhal, and +50% coins. Every round, the Daily sea and the four coin species stay free for everyone.

The game shows ads: a banner on the menus and a full-screen ad now and then between rounds, never during a round. Rewarded videos (revive once, double coins) are always optional.
