We just released a new version of out Four in a Row app integrating the 2D and 3D versions and adding other improvements like HD graphics.

We unpublished the 3D version and encourage our Four in a Row 3D users to upgrade to the new Four in a Row app.


We just updated our Slot Racing game on the Android Market adding the circuit editor. Now you can use your imagination to build the most incredible circuits.

It’s quite simple to use, you can press a track button to add it to the circuit. There is a “save” button to store the circuit (if it is closed) and a cross to delete the last track added. The editor supports the “pinch to zoom” gesture to zoom in or out. you can also slide your finger to change the viewing angle.

You can raise or lower the track with two buttons (up and down arrow), but there are also two special tracks, the “up” and the “down” that are quarter straights curved 11.25 degrees (90º/8). You can also add the “bridge” decoration to any elevated track.

If you play via bluetooth on a custom circuit, this circuit is automatically added to your opponent’s circuit list, so it’s very easy to share your circuits.

Circuits are stored on the “SlotRacing/” directory of the SD card. We created a simple XML format to define the circuits, and yes, you can create your circuit collection and share them among devices copying this folder.

If you create a great circuit and you want us to include it on the “Simple” or “4 Lane” category, send us your XML and we will add it.

Hope you enjoy this new feature!


We started this year working on our new game “Slot Racing”, a version of the popular 80′s and 90′s game. We already released a beta on the Android Market and it had 100k downloads in less than two months.

We are getting a great feedback of our users (and bloggers like Tecmovia) and we will keep improving the game.

Arpad ELO, creator of the ELO Rating System

Some people is asking us about the “ELO” and “Move Time” options on Mobialia Chess. ELO is an statistical chess rating based on games results playing against other persons:


Our Carballo Chess Engine has an estimated ELO of 2100 on a PC, playing against other chess engines. Those test results are shown on:


On a Nexus one (with 1GHz processor) with Froyo (Android 2.2) this sould be something similar. But in other (slower) mobiles may be lower.

If you select on the settings ELO 2100, the engine will be playing at his maximun strength; selecting lower ELO levels, the chess engine lowers its playing strength, introducing errors and reducing game knowledge.

We made some statistic analysis to determine the relationship between the errors introduced and the ELO level, so it should be something aproximated.

The move time is different to ELO, it’s only the time that the engine will be thinking for each move. To save battery the game does not ponder (think on opponent’s time).

We just released Mobialia Chess v4.0 including a new 3D board feature (in beta). It works only in landscape and this first version does not show board coordinates nor captured pieces difference.

At the moment we are using pieces models with a low amount of faces to be compatible with many different devices. We did some test with better models, but it was causing out-of-memory errors on low end devices.


We released a 3D version of our famous Four ina a Row game. It’s like our original 2D game and you can move touching the board, but you can also rotate the board touching on any empty region.

Features the same strong AI than the 2D version (so strong that we have a lot of negative votes saying that it’s impossible to win).

Update: 2011/3 both 2D and 3D apps will be integrated in one.


We just released a new Android app to track your Twitter followers.

One of Twitter’s lacks is that you cannot see who unfollowed you. This app solves this problem showing for each one of your accounts a list with your lost (and gained) followers.

Supports multiple accounts and also displays a graph with the followers count progression. It’s available for free at the Android Market.


On August 29th, the  Ex-World Chess Champion and chess legend Gari Kaspárov played and exhibition simul game with the Semp-Toshiba myPad tablet using our app Mobialia Chess.

This game was played at the Brazilian Federal District against 13 opponents with some politicians among them.

The event was a presentation of the new Semp-Toshiba myPad Android tablet featuring a 10″ screen and a Nvidia Tegra 250 dual-core 1Ghz CPU. This is the fist tablet device made in Brazil!

We are very proud that Semp-Toshiba choosed our chess app, and to celebrate it we released a new Mobialia Chess version with portuguese translation. Android tablets are great devices to play chess and we expect a big increment of tablet devices running our chess app.
