Expert Drone Day 6:
There are 2 rows with 3 smackers each. The middle drone is one square behind the top and bottom drones. What you want to do is move the middle drone to the same column as the other two. Then pause the game and draw the paths: the top and bottom drones will go in a straight line until just the squares just before the final smackers. When you reach that square, head diagonally to the edge of the map (upwards for the top drone, downwards for the bottom). Start and immediately pause again (like double-clicking on a mouse), then draw a straight path for the middle drone to get to the end. This should work.

Expert Smacker Day 6:
There are 3 rows with spots for smackers. Put your first 2 smackers in both spots in the top row. 2 go into the middle row spots, and the last one goes into the centre spot of the bottom row.

Expert Blocker Day 6:
Okay, so 4 rows of towerbot placement boxes. Put the smacker in the 2nd row and the blocker immediately left of it. Put the pointer in the 3rd row spot pointing downwards. Put the blocker underneath it in the furthest possible spot for it (it should be 1 spot above the bottom row of the map). The crusher has a pathological need to smash the blockers, even when going around them is better.

And that should be it!

Have completed them all. Thanks Jim! And Eric, will try Blocker Hard 1 as soon as it comes around. Sarah, I'll get Smasher, Blocker and Drone day 6 posted in 3 days' time!

I got lucky. I put all the smackers there out of frustration and saw the path, then put the blocker and saw it didn't change, so I let it run and it worked.

I still can't figure out Blocker 1 Hard though!

That last explanation was for Blocker 5 hard, by the way.

Alright, so this might be a bit complicated to explain but here goes:

I'm going to explain this by columns. There are 10 columns in this map. The first column on the far left is where the bots start. Place a smacker on the square at the top of that column. On the 3rd column, 2nd from top (just above a smacker square) place the blocker. Put the 2nd smacker on the top smacker spot of the 6th column, and the last smacker on the spot in 8th column (only one spot there).

The blocker creates a tunnel the drones have to go through to get past the first smacker, and for some reason instead of continuing to move, the first drone will stop to destroy the blocker, and because of that the smacker will destroy the trapped second drone. The 3rd smacker will take care of the 1st drone.

They were meant to unlock new levels. Now that they're stopping support for the game, the keys are useless. Also, I should have Blocker 5 Hard solution up in about an hour.

Thanks! Again, I'll have to try that next week as time ticks over faster here in Australia :P

Blocker 4 hard: Put all 3 smackers on the left section. Two of the drones will head up top, and the 3rd one will head by the bottom area. Put the blocker in the path of the 3rd drone (I put it on the last available space on its path). Let me know if that works or if I need to go into more detail.

I'll try it next week. It just ticked over into day 3 for me, so I need drone 3 now :/

I need blockers 1 and 2 and drone 3, all hard. Hopefully I remember what 4 and 5 of blockers are when they next come around so I can let you know what I put to clear them!

Shahar Cohen: Smacker day 7 solution. Put the first smacker in the first space the bots walk past. Put the second smacker on the 3rd spot (just after they make their first turn right). When they get to the next section where smackers can be placed (the two next on either side of their path), put the third smacker on the left box.
