In summary - three average and bland hidden object games for which I can only give a lukewarm recommendation because of the cheap bundled price; there are much better hidden object games on Steam, and I would rather pay more for a greater challenge and/or more sophistication.

This is a joint review for three of the developer's "Hidden Cats" games - Haunted Mansion, Spooky & Zoo - which I bought as a Halloween bundle. My total play time to complete all three was 25 minutes - in fact Zoo represents 14 minutes of the total, and my time in the other two games wasn't even enough for the Steam system to ask for a review. All three appear identical in operation:

- a single monochrome cartoon-style scene with 100 hidden cats (which are coloured in when found)
- a penalty-free hint button which highlights a hidden cat exactly rather than indicating a wider area, so not really a hint. If the player is zoomed in to one area and the cat is on another part of the scene, they won't see the highlighting at all
- a zoom feature which isn't quite good enough for some tiny or mostly obscured cats
- there are none of the special effects of some other hidden object games e.g. animations, colouring of parts or all of the scene (other than the found cats), or cats totally hidden inside or behind objects

In terms of the individual games, Zoo is the trickiest partly because a number of cats are either very small or mostly hidden behind something, and partly because of the number of other animal shapes in the scene; I had to resort to zooming in fully early on in the game. Haunted Mansion is the easiest and I only had to use zoom for the final cat; as others have mentioned, it seems to be particularly suited to children. And Spooky is somewhere in-between - I needed to use zoom only for the final four cats.

So, nothing horrible or broken in the three games, but nothing to get excited about or well entertained by either. I doubt if I will play any further games in this particular series.
