## VOI Reviews in United States

### ***** "RECOMMEND"
Fun; great, but sadly only 89 levels kinda expect more levels and some higher difficulty.
-- theonewho gotaway, 2025-12-28

### ****- "Entertained For Years"
I would play this game on and off for few years; take breaks when I got stuck but always came back to.  Finally beat all levels.  Found the background music to be mellow and relaxing.
-- bobbyd88r58t58, 2022-09-12

### ***** "Devs: Please make a Voi Pt 2!!"
This game is so good, it deserves a T2-esque sequel.
-- Luna Lunita Lunera, 2022-03-11

### ***** "Amazing!"
I love this game!  I really like the design and minimalist design.  Some puzzles are super hard and some are pretty easy, but that makes it so you don’t get too bored or frustrated.  I did get thru all the puzzles in just a few days.  I only wish it was longer, hopefully they come out with more packs to add to the library of puzzles.
-- Babylats, 2018-11-18

### ****- "Beautiful. Wish you could turn sound off."
This game is gorgeous, user friendly, and a real pleasure and challenge to play. Hits all the right spots for me. However, there are no settings within the app so you cannot turn the sound off. I like playing games while commuting and listening to podcasts, and with this game you cannot listen to anything else while playing. That’s the only reason for 4 stars instead of 5.
-- lilyelle17, 2018-09-12

### ***-- "Good"
I like solving puzzles without points, rewards, or timers. This delivers all of that. 

I want it to view my solution until I dismiss it. It’d be even better if the game outlined the final pieces so I understood my solution. It’s common enough for me to solve by accident, but the app instantly wipes the board to move to the next puzzle. This is rather unsatisfying.

Also, the sound can’t be muted. I have my own soundtrack I’d like to listen to while playing.
-- Gearloose2013, 2018-03-26

### ***** "Great Puzzler"
Sometimes you will immediately see the pattern and other times it feels more like trial and error until you’ve stumbled upon the correct solution, but overall I enjoyed working my way through the 88 puzzles in VOI.

If I had to find a flaw, it would be that VOI doesn’t backup your progress to your iCloud account. That makes me weary that if I delete the game there will be an update in the future that adds more levels and I’ll have to start from scratch.
-- cdkii, 2018-02-12

### ***** "Excellent for repeated plays!"
Like tangram puzzles but with the pieces changing as they overlap. Stays good even on repeated plays.
-- ClimbingGame, 2017-12-26

### ****- "Nice distraction"
Good distraction while waiting in line. My teen son is hooked.
-- Puppy's are awsome, 2017-08-07

### ****- "Good Game"
Good, creative game. Controls a bit sticky at times. I want more l"CHALLENGING levels. All in all, I liked the game.
