I, myself have read about/solved a few rebus puzzles myself recently; And from whatever I have read about them and learnt about them after solving, I can give the following tips:-
POSITION WITHIN A REBUS PUZZLE
One way of encrypting a Rebus is the positioning of the words and symbols, in terms of its place on the canvas area and to the other words and symbols in relation to it. You also sometimes need to think what other words might be used to describe a symbol, letter or word.
In the example 12″ is in the word DOOR, 12″ (Twelve Inches) is also
known as a foot, so we have the answer of: Foot In The Door.
HIGHLIGHTING WITHIN A REBUS PUZZLE
Sometimes you can draw attention to some part of the Rebus, by an arrow, text bolding or underlining, indicating where you should be looking for the clue.
In the example the arrow is pointing to the first word which is
indicating “The Beginning”, so therefore the answer is The Beginning
Of The End.
DIRECTION WITHIN A REBUS PUZZLE
A word can be spelt in a particular direction other than the usual like
left-to-right to reveal a hint to the solution.
This Rebus shows Two “Feet” in the Left direction, to give the answer
Two Left Feet.
SIZE WITHIN A REBUS PUZZLE
You may make use of large or small words or symbols to
convey concepts like big, small, skinny, wide, etcetera.
Take this Rebus puzzle below, the word “Deal” is big so it
represents Big Deal.
NUMBER(S) WITHIN A REBUS PUZZLE
You can make use of numbers and their
closeness in sound of 0, 1, 2, 4, 8, 10,
etcetera, to other English words.
This cryptic example shows 2 “Funny” 4 “Words”, and so the answer is
Too Funny For Words.
COLOUR WITHIN A REBUS PUZZLE
You can adjust the colour to be relevant in
the answer. Sometimes Rebus puzzles may make use of colour names like Rose.
In this extremely easy example “Tickled” is Pink so the answer is
STYLE WITHIN A REBUS PUZZLE
You can adjust the style of font to represent other
words such as tall, petite, thin, slanted, bold etc.
The “Skinny” letters in the example makes the answer is Skinny
SOUND WITHIN A REBUS PUZZLE
Your Rebus puzzle can be phonologically cryptic
(to do with sound). The sound might not always be exactly like the
answer, but it will always be close enough to recognise.
Take the Rebus below, the “2222”‘ when pronounced together
sounds like Tues, then with the word “Day” we have Tuesday
IMAGE WITHIN A REBUS PUZZLE
You can make use of images. The image
will definitely form part or most of the clue.
Take this One, the Rebus shows an “Apple” and the mathematical number
for “Pi” which gives us Apple Pie !
