The Pulsar Chess Engine plays Chess with multiple levels and five Chess variants: Crazyhouse, Loser's Chess, Atomic Chess, Three Checks and Giveaway(also known as Suicide Chess). The first few years of its development it only played chess, but over time I taught it the variants it knows. In its chess play it values mobility and active positions over just material(though its play is sound for whatever level is chosen in terms of standard material play) and with the variants, each has its own style.
Pulsar features levels of play from beginner to advanced and includes the rules of all its games including the rules of Chess. The game button - new game menu item, lets the user control the variant and difficulty. It defaults to Chess at Easy(lowest level) but remembers the current settings when the App restarts. There are some choices of chess pieces and board color schemes. This is the same Pulsar Chess program that i've developed for computers.
Pulsar began as a chess program and later learned variants. It ran extensively on two chess servers for many years both at chess and variants and from that I developed the system of handicapping it. The ratings on the board reflect strength I saw in rated play on handicapped bots. They are not 100% exact but generalizations I made from the various bots I ran at different settings.
As of version 1.3, all games played that end with a result or resignation are logged. Pulsar can't read PGN game files but the file can be exported out as an email attachment as well as deleted in App, such as to start the log file over. Previous versions only allowed mailing of last game.
If in the new game selector, Play vs. Computer is unchecked the user can move for both sides. This is to allow two people at same location to use the App as a board for a game and have the app enforce move legality and results for whatever variant is selected, such as a normal Chess game or a Variant.
Fix for latency when moving on some devices when sound is on

Great app. Exactly what I hoped existed now
I didn't think I would find an app that could play crazyhouse, much less beat me. This is exactly what I was looking for. Great app. Now I don't have to bore myself playin regular chess on my cell phone!
Just don't get fooled
This is only an app to play against. You cannot challenge another player, like for example "chess with friends". Who wants to play a computer all the time?
On the up side FINALLY there is an app for suicide chess and atomic chess!
Awesome sparring partner
Im a regular chess player approx 1700 uscf and I find pulsars style of play on the lower levels quit amusing and challenging. Its really a great training tool for beginners + its free.
The cons: a few bug here and there but if you e-mail the developer he is quick to respond and fixes up the issues.
I gave it 5 stars because I find the app highly addicting.
With Family Sharing set up, up to six family members can use this app.
