What Makes Light Cross – LightUp Puzzle Stand Out
Light Cross is a logic puzzle game using "light bulb & beam."
Set light bulbs on empty cells and illuminate all cells!
This is a great way to kill time!
BASIC RULES:
Tap any cell on the screen to place a light bulb in it. Light beams from the light bulb spread out in four directions and illuminate all cells in each direction.
Each stage is completed when all cells are illuminated AND the following 2 rules are both satisfied:
[Rule One] No light bulbs can be placed in the path of light beams from the other light bulbs.
[Rule Two] The numbered blocks show the number of light bulbs you are going to place in the adjacent cells.
It is a very simple but arcane puzzle game. Let's start playing now!

Player Experience Highlights
Community Insight:
Arguably too expensive Ive bought more than enough packs at 99 each that if we get bored replaying them, Ill just delete the game for awhile; we cant justify spending any more cash on this very simple game. The only complaint regarding gameplay is that if we restart a level, the marks Ive made in cells to designate No Bulb are cleared, and we have to go thru that whole process again which can be a lot on certain levels. This should be a second, optional clearing determined by the player. Otherwise, very fun, easy-to-mildly challenging puzzle game we can easily revisit over time.
This is one of VERY few reviews Ive written for an app, but we love this type of puzzle (whatever the official name is) and would love to see more! In this app specifically gameplay is really smooth, and theres an excellent scroll mechanic (which we cant say for a lot of apps). Its also the only game we have on our phone where we leave the music on. Its calming and fitting for the puzzle, and together with the background it actually adds to the atmosphere of the game? As if someone knew what they were doing?? What??? But seriously, this game makes us happy, and even happier when we see and hear the thought that went into making it fun to interact with. Support a smaller app developer and play! (Adding 3/1/20) Opened the app after a week of not playing. We forgot to mention that this game SAVES YOUR PROGRESS on puzzles, which is something else a lot of apps dont do. Love love love it.
Tests to the most simple on to the most complicated problem solving.
You can complete the first two free sets in a single day, then it wants you to pay one dollar for every subsequent set?? Waaay too expensive for how simple the game is. Was fun while it lasted but the cost is way too high.
The app is simple and easy to use. The puzzles are far too easy. Also, same music as developer's other apps.
The cost model is outrageous. You only get to play 1 level per section, without paying for the section. Its incredibly expensive per game. Shame. Ive beat all the games and will delete the app.
