Still struggling to come anywhere close to winning, but at the very least, I was able to discover just how very precious that fish was! That was a good, good idea. I offered the next fish to a second set of dolphins so eagerly, thinking I was going to win soon - and discovered how diabolical you were! What a game.
Also, the system you have created has an equilibrium of its own but it's slow to act, huh? Even though I feel quite lost when it comes to coming up with strategies, the option to 'Save' , 'Ask for hint' as well as see 'History' does help in making it feel more fair. Good job, again!
