Flappy Submarine

Far below the surface, a yellow mini-sub slips through a coin trail and threads past naval hazards. The captain's seat belongs to you in Flappy Submarine, an arcade game that sends the craft deeper with every pause and rewards long runs with a higher score.

How to play?

Tap to raise the submarine. Between taps, it sinks lower in the water, so depth changes on every move. Guide the hull past mines and incoming torpedoes, then pass through more coins to push the score higher. Distance adds up fast when the sub stays in motion.
