Hey guys am very new to corona/Lua. I am trying to a connect dots kind of game. Here there is a grid of dots (no. of dots increase at each level) and players need to tap space between two adjacent dots to form a wall. Could anyone please help me. I would really appreciate it.

Go through the beginner tutorials to learn how to put display objects onto the screen. Then write "for" loops to position the objects into regular spaces:

1
2
3
4
5
6
7

for i = 1, 10 do
  for j = 1, 10 do
    local dot = newImage("dot.png")
    dot.x = i
    dot.y = j
  end
end
