In Korokoro Puzzle: Happy Panechu!, the basic strategy is to first fill the screen with colored blocks called Panechus and then make them disappear by making a group of Panechus in one color come together to fill up the bomb meter. Then combine the bombs into mega bombs to blow up the screen big time. There are five different play modes to choose from. • Block Battle – Set off bombs to send blocks to the AI opponents screen. The first one to get a completely cluttered screen loses. • Knock-Out Game – Blow up bombs next to the enemy platform in the middle to harm him, bigger bombs means more harm. • IQ Puzzles – Clear the screen of Panechus in the least possible number of moves. Any panechus left on the screen and you lose. Unlike the other modes you can't make more Panechus appear with the A button and there are no bombs or bomb meter. • High Score Game – Gather as many points as possible in the set time by blowing up big bombs. • Time Challenge – Clear the screen in as short time as possible. The top right meter ticks up, when it fills, new blocks falls onto the screen.
