Addicted, to say the least

I love this game so much. I play every single day and I love love love the hard levels. Please port to android!!! I got a new phone but I kept my old one and all I’ve been doing on it is playing bull pen lol

Great!

Great game

Cute idea

But annoying execution. I found the solution to a puzzle, but it didn’t count because it wasn’t the one they chose. You have to solve the puzzle their way, not yours. Deleted. 😕

Overly easy then a guessing game

Every free level can be beaten within like 3 hours without hints before they hit you with a pay wall. The only way they could create any meaningful difficulty is by making the hard levels break the pre-established rules. Most of the time it devolves into a guessing game of where you have to place the two bulls required for every pen, row, and column. If you bother to use the hints in the hard levels, they throw some obscure clue about so many colors in so many rows, but is usually some bad advice. Not worth the 3 hours of your life, skip this one.
