Product Details

Mephisto Phoenix is the most powerful personal chess computer of all time.

Phoenix is bundled with a medium size 15.7" wooden sensory chessboard and comes in a modern glass touch screen design. It features both the newest computing technologies along with retro engines from decades past.

Onboard Wifi means it can stay current as updates are released. For example, the ChessLink app will be added in 2023 providing for integrated online chess play without the need for an external device.

About the Mephisto Phoenix

(See also this Blog Article for more about the Phoenix here.)

The Mephisto Phoenix is
a UCI based multi-engine chess computer, which provides access to a huge variety in chess gaming. With Shredder Neuronal and Stockfish NNUE, you see the world’s first dedicated chess computer using most modern neuronal engine technologies.

The module in its modern design comes with a large color touch screen made from real glass, matching its wooden board perfectly. Accompanied by the well-structured touch menu system it is meant to be the perfect home station for chess lovers of all ages, all playing strengths and all experience levels.  

Most powerful chess computer of all times

The Phoenix comes with 4 different Top-Class Engines on Board: Shredder 13.5, Komodo 14.1, Hiarcs 14.2 and Stockfish 15 NNUE. Starting from a very simple level, which is also suitable for absolute beginners, the system can reach a maximum performance of over 3400 ELO. In fact, there are countless options to adjust the playing strength to your individual needs. The system covers the widest playing strength range ever provided by a chess computer.  

Shredder offers a highly interesting new function with its fully automatic self-adapting playing strength with ELO rating. In this way you can continuously monitor your progress and see how much you have improved through training with the computer.

The evaluation bar beside the chess board tells you at first glance how the engine rates the position. Any blunders are quickly noticed that way and you always have a feeling on how good you do.  

Great opening training per your needs 

The machine comes with some different opening books: The standard one by Mark Uniacke provides you with more than 1.000.000 positions, all from master play. This is the biggest opening book ever provided by a dedicated chess computer.

The system is expanded with 23 classical chess computer emulations running at a high speed. Most remarkable is the “Mephisto Glasgow”, the legendary world championship program of 1984 - which runs on the MEPHISTO PHOENIX system at a speed of approx. 66 times faster than the original machine of the time.

With the speed bar you easily control the emulation speed or set it to the speed of the original chess computer, button and display layout follows the originals.

Updates for the System come via WIFI directly on the unit, and if you purchase additional software in the webstore it is installed as easy as with the press of one button. 

The Mephisto Phoenix is the right unit for you if you 

  • Wish to own the most powerful chess computer ever made, building a bridge between past glory days and todays modern style of playing chess
  • Are interested in modern engine technologies, e.g. NNUE Technology and see how they evaluate
  • Like to play with retro chess computers and to see how these programs perform on a modern hardware

MEPHISTO (Tournament Style) Sensor Board

The MEPHISTO Tournament sized board is a very flat sensor board with move indication by 81 single field LEDs as well as extremely comfortable fully automatic piece recognition. The chess board is Mephisto branded as well and board colors are finetuned to match the module and the pieces. The noble sensor board convinces by its high recognition speed and reliability. During the game, it is not necessary to look at the display of the chess computer due to the brightly lit 4 LEDs per playing field.

Daniel Dabney
Good hardware, iffy software

The board and the pieces are very nice, and it's a treat to see the position on the board automatically reflected on the display. But the software is buggy, and the interface peculiar. My main use case is to set up interesting positions I find in books and magazines. I then play, with frequent backtracking after the machine punishes my blunders, until I learn enough about the position to play it reasonably well. Perhaps it's possible to do this gracefully, but if so I haven't been able to figure it out. This sort of "play from here" just doesn't seem to be supported the way play from the initial position is. You don't seem to be able to get an equity score for the set-up position. The lights on the board don't work, and the display always seems to be telling me (in itty-bitty type) either more or less than I want to know. I gather that the gee-whiz feature of the system is its ability to use a bunch of different current and legacy engines, but it seems to me that you'd have to be a real computer chess maven for this to be really interesting--it certainly isn't to me.

Thank you for your review of this product; this feedback is helpful.

Please make sure you are using Mode --> Position to start a game from a position.
The reason the score does not update is that it is dependent upon the engine used. See page 9 in the electronic version of the manual under 'Special features of the rating bar' for more information on that.

Please reach out to us via our website communication so we can explore this with you in more depth.

Almost up to date technology, user documentation is poor.

The construction and craft quality of the Mephisto Phoenix is excellent. The Tournament Board and pieces are excellent and functional. But the User Interface with the computing hardware and software is pretty much an ongoing struggle to "learn how to play Chess" with this system. The use of the term "Profile" is never clear and has different meanings depending on the context. The documentation appears to be written by a non-native English language speaker (German?, Norwegian?, Chinese?). My 8 year old granddaughter can write clearer than this. The organization of the manual is not logical and requires repeated readings and searches to find a topic. And with no Index to the manual, it just frustrates me to look for a topic. Another thing, can the AI in any of these programs accept a resign or draw from the User or that matter can the AI interface ever resign or offer a draw? I cannot find any reference at all as to when the AI will resign. One more item. The UI can "get lost" when the User goes back and forth between the menus looking for something or resetting a "profile" etc. and at some point the UI is so lost it doesn't know where it is and no longer can play a game (no LEDs will light up on the Board, no pieces on the Board are recognized etc.) The Re-boot (Reset, Power On/Off) has often been used and forces me to reset my "Profile" again every time. I fully expect the developers to make the necessary patches to version 400E of my UI to correct these issues or this the Mephisto Phoenixx will be a commercial failure for anyone without supreme patience and a advanced education degree in interfaces.

Thank you for your review of this product; it is so helpful to get this feedback! As this is a new product for us, we're still learning more about how to use it and ways we can suggest improvements to Millennium. Please contact us directly through our website so we can provide more one on one support to review and document in more detail the issues you've presented here.

Assessment of the Phoenix:

I write this review as a person who has been playing chess for 50 years and used many chess computers throughout that time. My ELO is around 1900.


1) excellent chessboard recognition of the piece movements
2) strong engines as advertized - I played Mephisto against Fat Fritz and it drew every game fairly easily
3) Nice clear user interface

1) no programmable time controls; only presets which is an obvious weakness to other computers that cost 10% of this price. Why? Just write three more lines of code

2) No easy analysis functions after the game is over. Again, Why? $40 software does this but not here

3) Lots of to do about legacy UIs and emulation -- why? No one cares about 1980s user interfaces ... a bit like Microsoft promoting typewriters

4) User manual appears to be written by an 8 year old -- completely useless and not well thought out. You basically have to self teach by navigating. Again why this gap?

5) The UI itself is merely acceptable bordering on archaic. The resolution is good but the layout is all wrong, again, 1980s navigation. The clock timers are good but need to be larger, one should be able to scroll the entire move list, and why not a move counter?

6) Why market an opening book that is old and needs updating? 1 million moves is a drop in the bucket. The other software engines out there expose it in the opening.

In sum, you can tell all of the investment went into the board technology which is great, and less so into the user interface which, though improved resolutions, is still built on the old UI templates from 1990. Hire 21st century developers please who can improve the UI and navigation. Then, you won't have to write a 30 page user manual. The number of pages reflects the amateur design and clunky navigation.

All in all, I like it since there is nothing like this on the market. A 3400 rated + table top is great. But, it could be so much better. For the price, one demands a Mercedes, not a Chevy.

Great technology, poor documentation.

I am very impressed with the technology of the Millennium Mephisto Phoenix but the developers forgot to document how to use the technology. There is only about 20 pages of useful instructions where there should be about 150 pages minimum to provide the necessary information needed to enjoy the full experience. From Wifi issues to needing to avoid hitting new game if you want to save the game to PGN are just a few examples of lazy documentation or missing documentation. Hopefully, Millennium will pick their game up and properly document the features and how to use them in the near future. Until then, I would avoid the purchase.
