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.
I got really stuck on level 4 until I realised you could jump over two bubbles at one time. I don't think you can solve level 4 without that.
Level 5 puzzled me for a while, so I made a spoiler.
Far right circle jumps two spaces left.
Bottom centre circle jumps three spaces up.
Far left circle jumps two spaces right.
Top circle jumps two spaces down.
Far left or right circle jumps the other two.
