I decided to create a silly Scrabble variant played with only vowels.

Overview

Vowel Scrabble is one of the silliest Scrabble variant that is played with only vowels. The tile bag consists of 100 vowels, with 20 of each A's, E's, I's, O's, and U's, all of which are worth one point (no point values printed on those tiles). There are no consonants (even for the Y) and blanks in the tile bag. There are multiple catches for this variant. First of all, Vowel Scrabble is always played using the international Collins Scrabble Words (CSW) lexicon, which features 16 words with only vowels, as opposed to just 6 in the North American NASPA Word List (NWL), more than double the number of words in the latter lexicon. Those words including: AA, AE, AI, EA, EE, IO, OE, OI, OO, OU, AIA, AUA, AUE, EAU, EUOI, and EUOUAE (AA, AE, AI, EAU, OE, and OI are also valid in the NWL lexicon). All of those words can be found on a paper and can be shown during the game without learning them first, since there are only a measly 16 words in the entire list.

Here is the full list of 16 vowel-only words with definitions:

• AA - A Hawaiian word used to describe a type of lava, consisting of basaltic rock

• AE - Scots for "one"

• AI - A three-toed sloth, Bradypus tridactylus, endemic to forests of southern Venezuela, the Guianas, and northern Brazil

• AIA - A South Asian female servant (alternative form of AYAH)

• AUA - A New Zealand mullet fish, Aldrichetta forsteri

• EA - Archaic form of EAU (see below)

• EAU - French for "water"

• EE - Scots for "eye"

• EUOI - A cry of impassioned rapture in ancient Bacchic revels

• EUOUAE - A mnemotic used in medieval music, coming from Latin words saeculōrum and āmēn (pronounced /juːˈuː.iː/)

• IO - An exclamation of joy or triumph (also an alternative form of YO)

• OE - A small island of Scandinavia, Scottish Gaelic for "grandchild"

• OI - Exclamation to get someone's attention

• OO - Scots for "wool"

• OU - Afrikaans for "fellow", "guy"

There are also several rule chances as explained below.

Rule changes

1. The player who draw the vowel closest to A comes first. The order is: A < E < I < O < U.

2. There is no 50-point bingo bonus, as the longest word, EUOUAE, has 6 letters, which is less than 7 letters in length. Instead, there are two bonuses for playing specific long words: 2-point bonus for playing EUOI, and 6-point bonus for playing EUOUAE. Those bonuses are multiplied by double or triple play scores.

3. If all of the players have no more legal moves available, they never subtract their scores from their remaining tiles unless the bag is emptied. If a player played the last tiles out, they add the score from your opponents' tiles multiplied by 4 instead of 2. So in two-player game, the maximum score you can collect from your opponent's rack is 28 points from your opponent's seven unplayed vowel tiles.
