6) Andrey«morozec» Morozov (Russia, Samara) - WD My Passport Ultra 4TB.

We congratulate you all!

However, the other participants are still too early to relax, and it’s too early for us to sum up the final results of the championship. There is still a week of the Sandbox, and according to its results the best 6 participants will also receive prizes. We remind you that the finalists will continue to participate in the competition informally.

Last week before the Finals

Round 2 has finished successfully, and it means that there is less than a week until the Finals!

Games in the Sandbox now include 3v3 games with nitro.

Congratulations to everyone who made it into the Finals, but do not forget that those who didn’t, still can do so through the Sandbox. To do so, you have to be among top-10 in the Sandbox, excluding current finalists. You can see your progress on a special page. Also, there is a page to see Sandbox results for finalists only (link).

Good luck everyone and see you in the Finals!

Round 1 is over

Round 1 is over. In total for 2 parts each strategy has played 84 times.

Unfortunately, there was an issue with on of the participants (leloy) who did not make it into Round 1 despite high place in the Sandbox. So, we have decided to automatically promote him to Round 2. Also, since number of participants must be even, there will be 302 participants in total in Round 2 (301 of which will be top participants of Round 1).

If you do not get into their number, do not get upset. You still have a chance to get the T-shirt. For this, at the beginning of Round 2, you need to be in the top 60 Sandbox participants except for the mentioned 302 people. Within a few days we will add a special table, where everyone can track their progress.

And now begins the second week of beta test and also begins the hot time for adapting your strategies to the changed rules. Nitro is now available in the Sandbox games.

Round 1 is coming!

There is a little time left until Round 1 is starting!

It so happened that we could not get the planned 1080 participants. The main reason for this was the dates (holidays) and the complexity of the task. Unfortunately, we would not be able to start the competition as RAIC 2018 if not in these dates. We tried to approach this championship as responsibly as possible, although we thought that it could be like that. Although, according to numerous reviews, the game was liked by everyone, which we are happy about.

So, in Round 1, all or almost all of the strategies will take part. (The system is arranged in such a way that the number of participants in the tournament stage must be a multiple of the number of participants in one game.)

We remind you that the games of the stage will be played by waves. Each strategy plays exactly once for the wave. For the victory in the game, two points are given, for the defeat is zero, in case of a tie, both strategies will receive one point each.

We wish everyone good luck. But if you still did not manage to get into the treasured top 300, you can always go to Round 2 and even Finals from the Sandbox.

We need your opinion

Hello everyone!

First, here’s a list of recent updates:

• Fixed a bug in simulation, when two robots collided, and one of them was jumping (see new version of rules)
• Added JavaScript package (Node 11.5.0), thanks to participants for PR!
• You can now see time/memory consumed by your strategy by clicking the language icon on a tested game

Besided, we created a survey, asking participants about moving the schedule. Your voice is important. The decision will be made on December 31.

The first week of the beta test came to an end. A lot of improvements and bugfixes have been made in this time.

We won’t make changes that could affect the behavior of the strategy in the game till the end of Round 1 and the beginning of the second beta week. However, we will continue to fix known bugs, and we reserve the right to change the mechanics of the game beyond the rules if we deem these changes necessary.

The rating of all participants in the Sandbox has been reset.

Good luck in matches!
