+## Summer
+
+It's Summer time! Enjoy the hot sun with some fresh cool blocks!
+
+### Summer levels ☀️
+
+During this season a new level type is available, **Summer levels**. In these levels, your
+blocks are served on a cool plate, making them freeze up!
+
+Make sure you remember what was where, because the blocks get slowly hidden!
+
+Have fun!
