6) On a wall is a grid of white tiles, 1" by 1". The whole grid is 20ft by 15ft. At the junction of each tile is a small black dot. Through various means you give them the following three pieces of information:
a) "Press at (20,16)"
b) A broken ruler which only shows the following values: 3Ka, 4Ka, 5Ka. The gap between 3 and 4 and between 4 and 5 is 4".
NB: If you press the wrong black dot you get zapped with magic.
7) Puzzles involving lots of cogs, pulleys etc. and you have to turn them the right way.
8 ) The PCs are locked in a dungeon with some other people on some spurious charge. In total there are 23 people. The lord is mad and decides to have some fun with them. The prisoners will be put in cells with no way of commicating to each other whatsoever. A jailer will come and take them, one at a time, to a small room with two switches which can be on or off (they both start off). Each time they go to the room, a person MUST switch one, and only one switch (either from on to off or vice-versa). They will then be put back in their cell. They can't communicate in any way.
The catch is that the jailer can take them in in any order, and as many times as he likes, and with any time interval between two trips. e.g. he could take 2 people in 20 times before he takes any of the others in at all, or wait a week without taking anyone in. In other words, you can't just wait a while.
If one of the prisoners, at any point, says to the jailer "We have all been in to the room at least once" and it is true, everyone will be set free. If they are wrong then something bad (what exactly is up to you) will happen. The prisoners all have a short time before they enter solitary confinement to discuss their strategy.
9) This is probably my favourite. The prisoners enter a large room. It is bare except for one wall. On this wall are three things.
1) An 11 by 10 grid of tiles, each with a picture of something on.
2) A small panel with a poem on it.
3) A large 3 by 3 grid, each with writing in it.
If the correct tiles are touched in the right order, the wall swings back and they can pass. (If you touch a tile when you shouldn't you get zapped by magic).
The tile grid. Starting from the top left and going from left to right and then doing the second row from the top from left to right, etc., the pictures on the tiles are:
i)Rose, Pie, Crown, Walrus, Iris, Diamond, Woman, Hawk, Shield, Fool, Horn
ii)Volcano, Fire, Armour, Fish, Hart, Dolphin, Prince, Star, Sapphire, Bread, Comet
iii)Lamb, Heart, Rain, Ant, Peach, City, Tiger, Orange, Pearl, Noose, Boar
iv) Topaz, Mountain, Bow, Cat, Mouse, Girl, King, Gold, Head, Opal, Elephant
v) Moon, Monkey, Troll, Plum, River, Compass rose, Monk, Fox, Lightning, Whale, Emerald.
vi) Air, Willow, Baby, Scythe, Knight, Axe, Farm, Cloud, Sword, Birch, Mongoose
vii) Apple, Ruby, Abacus, Feet, Centaur, Tulip, Lark, Bee, Ship, Dragon, Sun
viii)Eagle, Island, Aardvark, Cow, Man, Heart, Boy, Queen, Silver, Skull, Snow
ix)Garnet, Plough, Mace, Princess, Lemon, Hand, Serpent, Dog, Bear, Oak, Elm
x)Wind, Ox, Earth, Horse, Throne, Dagger, Lily, Conifer, Water, Swan, Sceptre.
2) The poem on the small panel say:
"The odds you will proceed are less than even;
The following incantation you must speak:
"Monashi Catalan Fibonacci Olmera"
But only those most worthy will it pass.
A three, a four, these aspects are a plane,
A third dimension beckons if you deign.
Yet even if a cube, best not forget:
The prime commandment is factorial yet."
3) The three by three grid of bits of writing of various length. The segments say:
"Boar, king, ruby, willow, star."
"When patience would first flee the night,
When elements take up the fight,
When fear stifles mortal might,
Three swords must come again.
But when? When?"
"Starts, People, Ashari, Animals, Dorrani, Vegetables."
Which symbols will you touch?"
"Read! Virtue, love and honour be your guide. Which lore will be your saviour? When shall the dead awake and claim their glory? If you would have power and glory, choose so that the second shadow of the sun's last setting obscures the heartland. If you would rule with benevolence and love, choose so that the third shadow of the moon reveals the splendour of paradise. Which will be your choice? Who shall tremble at the passage of your passing? As you must start you must begin and as you would govern, so must you rule. Choose as your heart does sing."
"The heavy rains show the way one must step. We must obey."
"Ardo, Veracity, Regalia, Okandar."
"Right two squares, up to the oldest, first left, third right and then down to the empty square where you began."
"Lion is hungry, lamb is fearful
Eagle in eyrie, ox in pasture,
Hart horn-crowned, hawk is swiftest
Swan the whitest, serpent coldest."
