Rullo is a great online number puzzle game from Crescentyr. In Rullo you have to make sure the numbers in each row and column add up to the correct figure at each end.
To do this you’ll have to remove certain numbers from the grid. Remove all the ones you need to make the numbers all add up correctly.
Click once on a number to get rid of it. To lock numbers in place you can click and hold them for a couple of seconds till the edges turn yellow.
You can also lock whole rows and columns by clicking and holding on the outside numbers, which can be especially helpful later in the game when things get really complicated.
Check out the in-game tutorial for more.
Rullo has both classic and endless versions. Enjoy!Julian Cheatle updated this game on 22 Aug , 2016.
