I am getting old, so it's nice to know that I can still be cool at something.
The game was released on Big Fish in 2008 and I have played it off and on since around 2009, so I have had many years of experience with it. The only other match 3 game I have found to be almost as unforgiving in the latter stages is the original Cradle of Rome - and I never finished that one. Maybe someday I will get back to it.
Someone who is a whiz at these games posted this about Caribbean Hideaway on the BF forum:
I finally finished...it took a complete restart before I could. What a tough game! Normally I don't mind if a game is timed, but as fast as you have to go near the end, it doesn't seem like a very accessible game to many. That aside, if you don't mind a serious challenge, this is a unique and well thought out game that can be played over and over.
If you are getting really frustrated (and who wouldn't be at this point?), maybe get away from the game for a while and go back to it when you are feeling more kindly disposed towards it. That helps me sometimes.
