Introducing the new Mindoku game client

Hey,

Mindoku Team has been working on a completely new game client for the past few months and today we are releasing the first beta version of it. Beta means that it should work nicely but might still have a few bugs.

Our first game room that the new client supports is Othello:

othello

As you can see the new client looks and behaves similarly to the old Java applet version but has a few very important differences/improvements over the old version:

  • It utilizes modern web standards (HTML5, Web Sockets, Canvas, etc) which are supported by modern browsers and therefore does not require any external plugins to work. It is very lightweight and starts instantly when you open up a game room. No more waiting until the browser launches the heavy Java Runtime Environment which is needed by the old game client.
  • Soon you’ll be able to play in Mindoku with your tablet or a smartphone. Browsers for the mobile operating systems (iOS, Android, etc) do not support Java applets but they support new web standards and that makes it possible to use the new client on regular computers and also on mobile devices.
  • The development is much simpler with the new client which means new features or changes can happen faster.

What are the modern browsers that support our new game client you ask? There are currently three of them:

  • Mozilla Firefox version 11 and up
  • Chromium version 16 and up (Google Chrome, SRWare Iron, etc)
  • Safari version 6 and up
Other major browsers that do not support these web standards yet but will add support in the future:
  • Opera starting from the version 12.10
  • Internet Explorer starting from the version 10

Currently only Othello gameroom supports the new client but we will be gradually adding support for other games too. The current game client that is built using the Java technology will be slowly phased out. You’ll still be able to use the Java applet client for some time but we won’t be adding new features to it.

We encourage you to try out the new client and let us know if you encounter any bugs. You can also tell us which game would you like implemented next with the new technology!

Cheers,

Mindoku Team

 

UPDATE: Opera has now released the version 12.10 which means that IE is the only major browser that has yet to implement support for previously mentioned web standards.

Play Gomoku and Othello against a computer!

Hey,

We added a possibility to play Gomoku and Renju and Othello against a computer. To challenge a computer, just go to the gameroom and invite a user named “Computer” to play. There are two computer users in both gamerooms.

othello-gameboardgomoku-gameboard

The reasons why we created this possibility are as follows:

  • To create an option for beginners to try the games out without a risk of losing rating points.
  • Possibility for advanced players to spend time when there is nobody else in the gameroom. You can also challenge yourself to find out how many moves you need to win the computer or if you could fill the whole gametable with buttons 🙂

There are only two computer players in those gamerooms because we prefer human players to play with each other (if there are 3 or more users) rather than with computers.

In the near future we’ll add this possibility also to:

Stay tuned!

Cheers,

Mindoku Team

Dario De Toffoli reclaimed mind sports Pentathlon World Champion title after 10 years

XVI world championships in mind sports pentathlon, better known as the Pentamind world championships was won by italian Dario De Toffoli with 489.14 points out of maximum 500. De Toffoli destroyed the field of more than 200 players from 32 different nations beating silver medallist Francisco Paco Garcia De La Banda from Spain by 22 points. The bronze medal went to James Heppell from UK who lost silver by mere two points.

The most prestigeous multievent tournament in mind sports lasted no less than nine days and 104 hours with more than 50 different mind sports played from which five best results were summarised for each participant for the overall standings. The event was led for most of the time by englishmen James Heppell and David Jameson, before De Toffoli took over in the seventh day when winning an aquire tournament in a style and increasing his points tally to a whopping 485 points.  There was no real danger for the italian legend since then and he even got some extras in the final day with third place in lost cities. The other events in the De Toffoli´s top 5 were oware, backgammon and mastermind. With this great victory the italian became only third person in history who has won the prestigeous title more than once, the englishmen Demis Hassabis and David Pearce being the others. As the title was first time won by De Toffoli already in 2002, the ten years gap between world champion titles is an unique record in the event. De Toffoli now has 8 medals in the Pentamind – two golds, two silvers and four bronzes – an achievement which is also a record.

11 participants did collect more than 400 points:

1) Dario De Toffoli, Italy

2) Francisco Paco Garcia De La Banda, Spain

3) James Heppell, UK

4) Andres Kuusk, Estonia

5) Ankush Khandelwal, India

6) David Jameson, UK

7) Tony Niccoly, Italy

8) Michael Dixon, UK

9) Tim Hebbes, UK

10) Matthew Hathrell, UK

11) Alain Dekker, Republic of South Africa.

Non-consecutive Little Odd Fish Killer Sudoku

There are lots of different types of sudoku that are developed every year. It’s possible to keep the look of a regular sudoku and add some rules that will give totally new dimensions to these sudokus. As much as there are sudoku types, there are the same amount of different names to them.

The name of a sudoku has to tell you what it’s about. For example, if the name is non-consecutive sudoku, then there is an extra constraint that consecutive digits cannot be next to each other.

There is a competition at the logicmastersindia.com website this weekend until tuesday, and it’s all about killer sudokus. Killer sudoku is a sudoku that has extra areas in which the sums of all digits must match a specific number. The competition is about some new variants created by Stefan Heine from Germany who is one of the best sudoku constructors in the world (in my opinion). It’s worth to give it a try, because this competition has some style.

The name of a competition is Killer Shootout and sudokus in this competition consist of birds, fishes and compasses. One of the sudokus there has the coolest name I’ve ever seen: Non-consecutive Little Odd Fish Killer Sudoku. You can see the sudoku here:

Non-consecutive Little Odd Fish Killer Sudoku

There are some extra constraints and the name actually tells you what it’s about. It’s non-consecutive, there are some fishes where you can only write odd digits and it’s a variant of a killer Sudoku named little killer. The numbers outside the grid provide the sums of all digits in the indicated diagonal direction. Awesome!

I am participating in this event and hope to see you there!

 

Cheers,
