Read full descriptionHide full description
HappyHill is a casual and relaxing puzzle game. Your goal in HappyHill is to recreate the pattern for each puzzle in as few moves as possible or before the time runs out. Challenge your memory and see how easily you can recreate the patterns. When you get it right it's a relaxing win for your memory. Easy to use controls, drag a piece on the gameboard to move it to the wanted destination. To use bonus items press on the icon in the lower right corner of the screen. If it is empty you need to get more bonuses. Use the crystals you earn to get more moves if you are stuck. Or get more time with the solution by getting a hint. If you solve the puzzle with fewer moves than you have available you will earn crystals for each move you don't use. If you solve a time based puzzle you will earn extra crystals for not use all the seconds you could. Enjoy the relaxing and challenging puzzles in HappyHill to keep your mind sharp! Now updated with a new icon and some more stability features.
