Challengers are given a word that they must type using numbers to coorospond with letters. In other words counting their position in the alphabet.
For example the word dog would be 4157. The word regular would be 18572112118.
This challenge may not work in all languages. For languages with accents and other marks, try to omit these characters if possible.

Hello,
I like this idea, and I'll also submit one I've had for a while just because it's quite close to yours.

T9 challenge:
You are given a word, and you should type it, simulating a T9 input system, used on old phones with only a numeric keypad.

Normally, we have 2 for A, 22 for B, 222 for C, etc... But I think we can simplify this for Duck racing where you need to type only one number.
For instance, dog would be 364, cat would be 228, etc...

It would probably be good to limit both to relatively shorter words, typing a 10-letter word is overdoing it.

I think both of these ideas could work in all languages, as long as translators have a way to provide mapped lists. I.e. for your challenge, it may be something like this in English:
A=1
B=2
C=3
etc...

It may be completely different in another language (mostly thinking of Russian/Serbian here where a different alphabet order is used).

For my idea, I'm thinking of a similar format, it's just that here you'd provide which letters map to each number, so numbers would take the key here. For example:
2=A, B, C
3=D, E, F
4=G, H, I
Etc...

Oh yeah that challenge. Another more clear name for that could be keypad alphabet.
Personally i like the idea of having long words just because of the stress factor but I can see how that would overwhelm a lot of people or put them off from it.
Maybe words that are 3 to 7 characters? Of course it also depends how many letters starting from j are present. So maybe instead the challenge should analyze how many number presses it would take and choose words within a range of that rather than word length.

Hello,

I like the idea ! But I prefer Nikola's version, and a single digit for each letter. So DOG would be 364 (not 36664), CAT 228 (not 22228), and SKI 754 (not 777755444).
Now that we have a dictionary to pick words from, it's perfectly doable.

I prefer this version because I can't easily draw a word a random based on its length in T9 or alphanumber digits. Having the rule 1 letter = 1 digit makes it much more manageable. Otherwise, as you can see above, a simple 3 letters word could have up to 9, 10 or maybe 11 digits, which isn't that cool (worst cases I have in mind: ZOO, SOS)

Long live T9! One more thing people under 20 won't ever know. 😁
