Glisse banquise, on explique et on joue

About Pengo Jump, from BoardGameGeek:

Jump from one iceberg to another with your penguin friends to reach the ice floe. The main game board is a dual-layered tile with an opening on the layered side that allows ice to be shoved through and onto the main board. Players take turns drawing an Ice Chunk tile randomly from a bag, and then sliding the tile onto the sea board. Similar to games where coins are dropped and pushed by a mechanical arm, players are pushing the ice chunks in so that more of them touch, creating a ‘racing' lane without knocking pieces off the board. When two chunks meet, you'll have the opportunity to move penguins closer to the iceberg. They can hop to any ice chunk that touches their tile. They can even slide on the frosty, icy tiles as long as the tiles are touching and no other penguin is blocking them. In cooperative mode, players try to get all the penguins across to the the iceberg. In adventure mode, players use extra tiles with sea lions on them as a blocking mechanism - making saving the penguins harder. It can also be played competitively with players moving their own penguin, while trying to knock others off the board. -description from the publisher
