GungHo Online has released a scaled-down, free-to-play version of Puzzle & Dragons X on the Japanese 3DS eShop.
Battle Puzzle & Dragons X includes a "Battle Mode" identical to that seen in the main game, which features "Fixed" and "Free" contests. In these you can customise your team of monsters and also battle against players who own Puzzle & Dragons X: Kami no Shou and Puzzle & Dragons X: Ryuu no Shou, the two versions of Puzzle & Dragons X.
There's also "Challenge Survival" mode based around three difficulty options. Success in this mode will earn you new beasts and evolution materials, the latter of which can be used to power-up your team.
Battle Puzzle & Dragons X is being positioned as a demo of sorts, as data from this version can be transferred to the full game, should you choose to upgrade.
Would you like to see Puzzle & Dragons X adopt a similar approach for a western release, assuming that it happens? Share your thoughts with a comment.
