A solitaire Syllablast puzzle is based on four words, each containing four syllables. These original four words are divided into a total of $16$ syllables that are then placed in a $4$x$4$ grid. Each syllable has a location identified by its $($row$,$ column$).$ The player can swap the location of two syllables. The goal is to make a sequence of swaps to reveal the original four words $($when read from left to right$)$ that were disassembled to create the board.

In the initial configuration, none of the syllables in the first column are the first syllable in one of the original four words. Board State #$1$ below represents the initial configuration, formed from the words $$af$,$fil,i$,$ate$,$im$,$mac,u$,$late$,$in$,$vis,i$,$ble$,$ and $$un$,$der,wa$,$ter$.$ As you can see, each word has four syllables, separated by commas.

Board State #$1($swaps: $0,$ score: $0)$

ter ate ble der

fil in im i

i late mac un

u vis af wa

Board State #$2($swaps: $1,$ score: $2)$

ter ate ble der

fil u im i

i late mac un

in vis af wa

Initial Configuration Swap $$u$$ and $$in$$ syllables

Board State #$3($swaps: $2,$ score: $4)$

ter ate ble der

fil u im i

af late mac un

in vis i wa

Board State #$4($swaps: $3,$ score: $5)$

im ate ble der

fil u ter i

af late mac un

in vis i wa

Swap $$i$$ and $$af$$ syllables Swap $$im$$ and $$ter$$ syllables

With each swap, the score increases, but note that a swap could decrease the score if a properly located syllable is moved out of its location.

Counting Swap Moves

Until the puzzle is solved, Syllablast records the number of swaps $$ and in addition computes and displays the player$$s score.

Once the puzzle is solved, the player cannot make any more swaps.

Puzzle Reset

The player can reset the puzzle to its initial state: both the score and the number of swaps is reset to $0,$ and the board is returned to its initial configuration.

Undo Swap

The player can choose to undo the most recent swap and can do so until the Initial Configuration appears once again.

StoryBoards

Mock$-$up some sample GUI images to visualize the experience from the point of view of the player, showing a sample board state, the number of moves so far, the player$$s score, and controls that the player will interact with when requesting swaps. When a player has completed the puzzle, a congratulatory message must appear in some form and the puzzle will become inactive until the player chooses a configuration to play.

Initial Configurations

These are the three configurations that you must allow the player to choose from.

Configuration #$1$: $$in$,$vis,i$,$ble$,$im$,$mac,u$,$late$,$af$,$fil,i$,$ate$,$un$,$der,wa$,$ter$$

Configuration #$2$: $$ex$,$am$,$in$,$ing$,$re$,$in$,$force,ment$,$in$,$for,ma$,$tive$,$ma$,$te$,$ri$,$al$$

Configuration #$3$: $$me$,$chan,i$,$cal$,$cal$,$cu$,$lat,ing$,$im$,$me$,$di$,$ate$,$di$,$ag$,$on$,$al$$
