Fill in the missing numbers with the digits 1 to 9. A diamond shape in the middle means that the four numbers around it add to 20.
Each uses a different way to add to 20, i.e. if there is already 1 + 3 + 8 + 9, then there will not be another using the digits 1, 3, 8 and 9 (in any order).
The same digit isn't allowed to touch, even diagonally.

Hint: The diamond on the right side can only be 2 + 3 + 7 + 8.
Place letters into the grid such that every row, column, and 2x2 block has letters (in any order) that form a common word.
Each letter is only used once, and no letter is repeated in the rows/cols/blocks.
Letters allowed: W A R M T H.

Hint: Row 1's missing letter is A which makes Column 4 a little easier to think about.
Across: OVAL, WISH, TOMB, REAL
Down : VAST, BROW, LIME, HALO
Boxes : VOWS, HAIL, BRAT, MOLE
Note : Other anagrams of these words are OK as long as they don't change the answer grid.

A grandfather and his grandson have the same birthday date.
For six consecutive birthdays the grandfather was a multiple of the grandson's age.
How old were each at the sixth of these birthdays?
Hint: For one of the birthdays, the grandson was 5.
Grandfather 66, grandson 6.
61 1 (61 = 1 x 61)
62 2 (62 = 2 x 31)
63 3 (63 = 3 x 21)
64 4 (64 = 4 x 16)
65 5 (65 = 5 x 13)
66 6 (66 = 6 x 11)
So on the sixth birthday, they are 66 and 6 respectively.
Using the BrainTracker grid below, how many words can you find? Each word must contain the central
U and no letter can be used twice, however, the letters do not have to be connected. Proper nouns are not allowed, however, plurals are. Can you find the nine letter word?
Excellent: 50 words. Good: 35 words. Average: 25 words.
