Numberblock Castle

Lever / 5
There's a lever, but nobody can reach.

4 thinks 5 can help

4 + 1 = 5

5 pulls the lever

Tunnel / 6
There's a die and 6 paths. 4 thinks 6 is good with dice

4 + 2 = 6

There were 3 spots, so 3 counts 3 rooms

1,2,3 and 4 go in

Doors / 7
7 would be VERY lucky to have, since there's 7 doors.

4+3=7

7 falls on door 7 and there's 8 flags...

Flags / 8
...4 says they needed someone with VERY LONG arms to stretch that high.

4+3+1=8

8 makes a basket, and carries 2 over the green (maybe acid) liquid.

Door / 9
1 and 4 try opening a door, but 4 says they need a BIGGER SQUARE

4+3+2=9

Hole / 10
They get crowns and need to fly out.

Ten can.

4+3+2+1=10

10 flies out.
