Adding new variants

Add any number of checks, like 10 check

dragon fly chess it takes place on a 7x7 board, there are no queens and the setup goes like this, rook, bishop, bishop, king, knight, knight, rook, mirror this setup for black, pawns may not do the double step move, pawns may not promote to a queen, pawns promote on the first or 7th row.

Variants gives players the opportunity to design new variants themselves, play them (unrated), and submit for review by team CGA (custom game admins), for a chance to have one’s game listed.
How to create custom games:Hit 'A' on your keyboard (or open any game), click the Edit Position icon at the bottom right.
Create a starting positionChoose board dimensions (anything from 2x2 to 14x14), and set up pieces (including 23 fairy pieces) for up to 4 players.
Bricks and transparent bricks are also available, as well as dead pieces (serve as removable obstacles), or bounty pieces (live pieces that belong to a dead player, the difference to dead pieces being that they give points when captured).
Additionally up to 2 players can be set to be zombies, eg a computer will move them, according to the zombie type. Zombies can be made immune, meaning their pieces cannot be captured (these are extremely powerful “moving walls”).
(The blue knight will make random moves and cannot be captured.)
The royal piece must not be a king, it can be set to any one piece for each player.
Add rules:There are some two dozen rules available which can be combined.

Of course there are limits, if a variant requires additional rules (say something like ‘backwards pawns’), those would need to be coded by us first.
New rules are coded in a way that they can be used as building blocks. For example, Racing Kings can be ‘added’ to any game, so you could create 3player atomic racing kings or whatever.
Any player can create such a game and play it casual. Admins can add games to the list of variants, and listed games may be played rated.

For listed games, admins can set up a variety of further properties, such as name, url, icon, teaser text, how-to-play descriptions, sorting, categories, which rating to use, etc.
Team CGA has become increasingly strict and only accepts very well thought out and fun games. They also remove games again that don’t get much attention.

Please read the requirements carefully before submitting your variant.

I made it by using invisible walls (borders)

Thank you so much

you should add custom promotion

But we still can't both see our pieces at the bottom at same time. What's the problem guys?

they did! you can allow custom multiple promotions! just click the edit button, and type in how many pieces you want! don't forget it's names, the letter of that piece, example: R = rook
