“This game helps me with numbers. Great!”
“Great puzzle game. I'm fool.”
“Lewds linked to game play in only the loosest sense. Complete puzzles to win points, use a tiny amount of points to unlock each girl, all scenes are available right away. Art is fine, and the puzzles are actually pretty…”

“Pretty challenging puzzles for being a hentai game. Luckily, if you don't care about the achievements, you don't need to complete all the levels. Otherwise, the animations are top notch so you won't be disappointed…”
“Let's just say the Free DLC has some nice content and had nice arts.”
“holy moly look at those magumbos”

“Meh. It has animations, though. Barely make it to a neutral rate. There are better games out there. In the game itself, getting to the lewds is fairly easy. Now, if you are here for the achievements, it might prove to…”
“Hello Traveler okay puzzle game but the important thing is you only need to get to lvl 20 to unlock everything For one who is a connoisseur of art, I can assure this one is of high quality. (the only weird thing is the…”
“This is an interesting game. Basically, you have to solve puzzles where you must use the numbers to fill up a board. If done successfully, you get a heart. 2 hearts unlock a girl. There are currently ten girls. I have…”

“I love these kind of puzzles and you only have to complete 20 or so of them to get to the goodies. Happy Numbers has 10 girls with 5 scenes each, some of the scenes are a little bit too weird for my liking (corgis,…”
“"Happy Numbers" is a departure from the stereotypical match-3 h-games that we all have come to love. Using a sudoku-esque puzzle-like structure brings about a much needed breath of fresh air in the community. While the…”

“98% of the game is just the puzzle and you can unlock all the scenes within a small portion of all the levels. The lewds are fine at best and the rest of the entire game is just completing the number puzzles with…”
“The game may be short and simple but at this price tag it's worth the excellent quality of cg animations. This studio (Is HappyGames related to or a rebranding of Mature Games? I'm not sure, haven't looked too deep into…”
“Awful. You unlock all the girls and scenes insanely quickly and then there like 50 more levels with achievement for no reason and with no motivation. Actual Joke.”

— a player, Steam review · 2 hrs played“A fresh approach to the already over-saturated market of lower-budget puzzle games, Happy Numbers delivers by bringing a new type of puzzling which requires thinking and planning ahead. Where mostly other mature, sexual-content related tagged games, simply rely on their x-rated…”
