Context: Planet Puzzle League; known in Europe as Puzzle League DS, and in Japan as Panel de Pon DS (パネルでポンDS ) ; is a video game for the Nintendo DS handheld video game console in the "Puzzle League"/"Panel de Pon" visual matching puzzle game series.  In North America, "Planet Puzzle League" is part of the "Touch!  Generations" brand; in Japan, "Panel de Pon DS" is marketed in the general "Touch!"  brand.  The publisher for the game is Nintendo, and the developer is Nintendo first-party developer Intelligent Systems, creator of the original "Panel de Pon" and its cult classic English-language adaptation "Tetris Attack".  The game was released in Japan on April 26, 2007 in North America on June 4, 2007, and in Europe on June 29, 2007.  The game was not released in Australia. Souko Ban Deluxe (倉庫番DELUXE , Sōkoban Derakkusu ) , known as Boxy Boy in the United States is a puzzle arcade game released by Namco in 1990; it runs on Namco System 1 hardware, and is based on the "Sokoban" game series, by Thinking Rabbit.  It is a graphically enhanced implementation of the then-8-year-old Japanese puzzle game phenomenon, and is the only implementation of "Sokoban" to be released in the arcades - and while it features all the rules of regular "Sokoban" it also has a timer which determines how long the player character, "Rabi-kun" will have to clear the current round, before the game ends - and even if the player decides that he or she has to start the round over, the timer will not be reset.  If the player runs out of time, he or she can insert another coin to continue from the current round, with a full timer; there are fifty-five in all, and the player can start from the first, twelfth, twenty-third, thirty-fourth and forty-fifth ones.  The five rounds whose numbers are multiples of eleven are also indicated with a question mark - and, after the player clears one of the five rounds whose numbers are multiples of ten, he or she shall actually get to see the following (question-marked) round.  If the player clears a round in enough steps (a step is counted every time the player pushes the joystick, or presses the Reverse Button to undo one of his or her previous moves), he or she will also receive a "Best Steps" or "Good Steps" bonus - and some of the music in this game was later reused in Namco's unreleased prototype game "Puzzle Club" (although it was never actually released in the arcades).
