dPS – Create a "matching" game with a hidden message

Das Puz­zle Spiel is a LaTeX pack­age (dps) for cre­at­ing a puz­zle, a mes­sage ac­tu­ally, and a se­ries of ques­tions and an­swers. The doc­u­ment con­sumer matches the ques­tions with the an­swers. With each match, an­other let­ter ap­pears in the puz­zle. Upon com­ple­tion of all ques­tions, the mes­sage hid­den in the puz­zle is re­vealed. The puz­zle is pri­mar­ily de­signed for the screen, but you can op­tion­ally cre­ate the game for pa­per.
The pack­age it­self is dis­tributed as a zip file em­bed­ded in the pack­age doc­u­men­ta­tion.
