Let your line sink, wait for a bite and reel in gently. Rush and the fish lose interest, though your line never breaks. There are 135 fish to discover across 20 lakes and seas, with different hours and weather to look out for. Bobber barks when he smells treasure, and some of the 198 finds are hidden inside fish.

Sell your catch at the evening market, fill customer orders and use the proceeds to upgrade your gear at Old Mabel's. Better gear lets you venture farther, from Willow Lake to the Abyssal Trench, where the adventure makes room for sea monsters and the Murk Gang's boats. Back home, you can decorate a tank and raise 26 kinds of koi. An idle mode lets Rusty keep fishing on his own.
The original Koi Frenzy Classic is included. Its one-minute rounds are about chaining catches and beating your high score, and they can earn coins and rare koi for your tank. The game also supports controllers and lets you switch between 12 screen looks, including crisp pixels, VHS and black and white.
