One thought! One dream! One Bubble! One Mercado! Yes, Ozzie Mercado is certainly a one and only, and his string of quality simple idea puzzle games is quickly getting into the Ultra Combo range. His latest is One Bubble, a soothing peg-solitaire variant with some cool naturalistic visuals and challenging puzzles.
Select a bubble by clicking it with the mouse. A bubble can only be selected if it has a neighbor. Once clicked, you must select the free space that will allow it to "jump" over a line of adjacent bubbles, eliminating all of them from the board. Each level is solved once only one bubble remains. There are 30 levels in all, each with a par score representing the least number of moves is a little reminiscent of Mercado's earlier Jump Me, but modifies both its mechanics and style just enough to come into its own. There's a nice balance of puzzles that will require a bit of experimentation to suss out, and ones where a little observation will lead to a perfect moment of "AHA!". Another nice touch are the photo-manipulations used as backgrounds. They're never distracting, but really contribute to giving One Bubble that zen office-toy feel, making it perfect for an afternoon de-stressing.
