100 Floors: level 61 is based on the time that is set in the middle. 6:30 is actuall 1830 in military time so your task is to build up the time at the top. You can over lap one block with another so head on over to your apple device and start building. To begin beating floor 61 you need to find the 1 then fill in the first block. After on the second block to create 8 you need to use the F and the L that is upside down.
Once you have completed the first two numbers the third one is a 3 which is the 3. The fourth one, which is the last one is an 0 so use the two L, one upside down one not then complete it to make a 0.
The completed number should be 1830.
