Puzzles with numbers and things

[snookersfun]

as this is taking way too long to be revived, an easy little round for now:

Round 213: battleships

I guess, everybody knows this game.
Below is a partly printed in grid (with some water spaces or parts of ships). On its sides are clues, as to how many ship-parts are in each line. Number of possible ships on right hand side. Ships can't overlap and have to be separated by water from other ships.

Please fill in the complete plan!
Have fun!

Closing R209 ...

Yesterday evening, Gordon was in top form and in a mood for intensive practice. For the whole evening he played frame after frame, total clearance after total clearance! In fact he was in a pattern of three: first he played reds and colours in ascending order - so red yellow, red green, red brown ... red black, red yellow ... until the final colours - then he played them in descending order - red black, red pink, ... red yellow, red black ... and so on - then a maximum total clearance. He did that until the club closed! By that time Oliver was fast asleep, Charlie was gone to the banana bar and Barry had lost the count!
Charlie was supposed to keep the score. Of course he got bored! So he made himself a tool to follow Gordon's progress easily. He took a ribbon of paper: 1 cm wide and 54 cm long. He glued the extremities so he got a sort of ring. He then started colouring squares - 1 cm x 1 cm - on the ribbon according to Gordon's progress, each square being immediately adjacent to the previous one. Much to Barry's astonishment he managed to record the three clearances of the pattern, without tearing the ribbon apart or turning the ring inside out! And when he reached the final black of the third clearance, he coloured the last square neatly adjacent to the first one! So he was ready fo follow Gordon's progress in the next round ...
What's the trick? Please explain this to poor Barry ...
Well, when Gordon finally got tired and Charlie was at the banana bar, a fascinated Barry decided to study this wonderfull ring more closely! So he took a pair of cissors and cut the ring along the middle line, in the length. So he thoutgh he would leave a ring to Charlie - half a cm wide but never mind - and have one for himself. Not so! Poor Barry was very frustrated! What happened?

Here is the "ring", Charlie made

You can reproduce it by taking a ribbon of paper, twist it once and glue the extremities. If you start drawing a line in the middle, and "follow" the ribbon path you will see that it has only one side and that you will come back at your starting point ...
To understand why Barry was frustrated ... take your scissors and cut your ribbon in the middle ... then if you like it, cut it again

Have fun!

Round 212 - Touching Balls

Barry, who owns Barry The Baboon's Ball Shop, has many snooker balls - they are of 7 different colours: red, yellow, green, brown, blue, pink and black. (Red counts as a colour here.)

He wants to place his balls on the table, so that no ball touches two other balls that are the same colour as each other. (For example, no ball can touch two reds, or touch two yellows etc.) He is very particular, you see.

Every ball must touch at least 3 other balls. Barry also wants to have at least 7 balls each touching at least 6 other balls.

Maybe we should try to colour this hexagon, before the boss comes back...

Let me start with red in the middle... Anyone to continue?

Round 212 - congratulations to Monique, snookersfun and abextra.

Next answer on the thread please.

Here is a clue how you might arrange the balls - you just need to choose some colours that work!

You can use as many balls as you like, up to a maximum of 20 balls. Show Barry how he might lay out his balls so they are as he wants.

"Experts", including chimpanzees, by Private Message initially please - anyone else, on the thread!

[davis_greatest]

Any chance of extending this? I've only just seen it.....how about until 9pm tomorrow?

Anyone who has 24 (or more) slaps, put it up on the thread! (I think 24 is probably the most though - at least that's the first number I came up with, but happy to see it beaten!)

[davis_greatest]

Congratulations, Monique. And congratulations to abextra, who also sent these answers, both also of 24 slaps.
