Hello dear coders,
Today we made some final changes to the AI Block Battle competition that should make it more balanced in terms of strategy options, plus some additional functionality that will require your bots to do a bit more thinking.
Here's a list of all the changes:
- Garbage line every 3 points, instead of 4
- Single clear points: 0
- Double clear points: 3
- Triple clear points: 6
- Quadruple clear points: 10
- Single T-spin points: 5
- Double T-spin points: 10
- Perfect clear points: 18 (still 6 lines sent)
- Every 15 rounds a solid line will appear instead of 20
- Every other garbage line has 2 holes instead of 1
- Single line clears will not count towards combo points, but will not reset them to 0
- A new move added: skip
The final point is the biggest change. Now you can collect a 'skip' by performing a double T-spin or a quadruple clear. You can use this skip by letting your bot output 'skip' when an action is requested and the current piece will be removed from the field and the action is skipped.
Let us know what you think of the changes. If everything is working as expected we will remove the Beta label and the finals dates will be announced.

That's quite a few changes! Will be interesting to see how this changes the game. One question: Is there any limit on how many skips I can collect? Thanks, cube

I'm very interested to see how it changes the game as well :P. No, there is no limit to the amount of skips, but they are quite hard to collect so there probably won't ever be many at the same time.

Please, give a picture, which show the move "skip", like pictures with moves "Double T-spin" in Rules. I understand English very little. This is only for double T-spin and quadruple, or I can skip any piece at any time, any number of times?

Ok so now that you did the last update, do you have some dates before the finals ? Because it's a pretty big update and we need to change our bots in consequence.

The dates will be announced when the competition is no longer in Beta, but expect to have several months before the finals start.

I haven't watched any matches, but my experience tells me that you should get rid of this rule: Single line clears will not count towards combo points.
The issue was that downstacking with single-lineclears was too powerful (no need to use multi-lineclears). You addressed this in 4 different ways: single = 0 points, garbage every 3 points, 2 holes for every other garbage line, no single combos. And because you did it in 4 ways, you overdid. Under circumstances, you weakened downstacking too much. If that's the case, we have the old problem: people will just leave a gap on the side (probably 2 wide with a few lines of 1 wide below -> spamming doubles and triples), and don't care about downstacking at all until they are near the very top.
Single line clears will not count towards combo points: This rule will favor 2-wides over 3-wides and 4-wides. 2-wides are very easy to do, so not a good idea. I don't know why a Double-Double combo should be stronger than a Triple-Single combo. 2 holes for every other garbage line makes big downstack combos almost impossible, so there's no need for this rule. Also I think, not enough garbage lines are sent.
Another problem I'd like to address: I watched the Warlight 2 finals and I didn't like that it was only best of 5. If you go for a best of 5, then give both players identical garbage (garbage holes on same places). The problem with 2 garbage holes per row is that the difficulty to downstack can be very different: as easy as 1-hole garbage if both holes are next to each other, medium difficult if there are exactly 2 filled cells between the holes, very difficult if there is exactly 1 filled cell between the holes. So the consistency of garbage could be a too big luck factor.
Every 15 rounds a solid line will appear: I am not a fan of this rule. Please change it back to 20 (or even bigger).

I like the changes, especially 0 points for Single lines / combos and the skip idea ... at first glance ☺ lets see how they turn out.

I got three more questions: If I have a combo of x and I clear one line, I still get x points, right? If I have a combo of x and I skip, I still have a combo of x? Can I output SKIP at any point in my move sequence or does it have to be at the beginning?

Also please don't go for a best of 5. If you do that and Bot A has a 60% win chance over Bot B then Bot B will still win in over 30 % of the cases which is quite high. I know it is time consuming but 500 matches would be a better indicator (about 2% chance of loosing if one wins 55%).

I also like the changes (just hypothetically, as I did not implemented a new version) Games with the current bots are quite comical by the way :)

- Yes, you still get the combo points, but the combo is not increased
- Actually that didn't happen until now, I fixed that. So a skip does not break your combo
- You can output it at any time, but that doesn't matter for the end result of the round.

There was a rule: two garbage lines added in one round can't have hole in the same column. Is it gone?

"If I have a combo of x and I clear one line, I still get x points, right?"
"Yes, you still get the combo points, but the combo is not increased"
Round 46. Combo = 1, one line is cleared. And not a single point was given that round.

I updated my bot and got first place, I bet that won't last long :D
One Remark: Could you ensure that the two holes are not placed next to each other (in the garbage line with 2 holes)? Otherwise you can get lucky and still clear it with one piece.
