The Hardest Easy Game
Play The L-Game: hwwmath.looiwenli.com/l-game
Edward de Bono is a lot of things -- an author, an economic theorist, a physician -- but he’s also a thinker about… thinking. His 1967 book “The Five-Day Course in Thinking” included a game that’s one of the hardest in the world, yet also one of the simplest.
The idea behind creating the perfectly simple, perfectly impossible exercise that turned into The L-Game was to distill a 2-player experience down to a constant churn of critical strategic decisions. By limiting the board to just 16 spaces with 2 L-shaped tetrominoes and 2 neutral pieces, the board can’t distract from the core task. And with so few rules -- really, just that you need to move your L piece to an open space and then optionally move one of the neutrals -- the focus is purely on thinking several moves in advance.
That level of abstraction is way, way harder than it seems. But by using experience to identify and organize some strategic guiding principles to moving in the L-Game, it’s possible for both players to play perfectly -- and forever.
As de Bono demonstrates in his course, that’s the same sort of approach we apply to almost everything we value. We think strategically about the groceries we buy, the relationships we have or want… if it matters, we employ some form of strategy. And the better we are at strategic thinking, the more likely we are to get the result we need.
And it all starts with a 4x4 board, two tetrominoes, and a couple pennies.

Just some clarification about only having 3 possible moves in the A, B, and C scenario -- yes, there’s also a fourth move (the L down the left side from the top corner), but it just mirrors the situation we have in A and B. By simply reflecting the L vertically, we open ourselves up to another immediate loss as orange places a horizontal L on the second row and kills our chance to make another move. Also, in move B, de Bono assumed that we would notice that Player 1 also moved the neutral piece from the top toward the bottom (since it can go in any of the open spots), which opens up a spot for Player 2 to go down the right half of the board. The neutral piece can’t be moved by orange *before* the L is moved, so that neutral piece had to have been moved by pink after Player 1 moved their L. Thanks for diving deep into these details -- and showing what strategic thinking is all about. P.S. -- Whether or not I put my pants back on for the rest of the video is up to you to decide.
he didn't have his pants on i guess
The breeze is gonna hit you in the nuts if you don't put that antibacterial silver tx2 fabric pants back on
take the L
but according to the rules, or what i understood, is that you could move the coin after you moved the L piece. And the coins seems like half the game. In your 'possible moves' you didn't move the coin at all, which would balance your enemie's possibilities..
@@kyden1329 Yeah you can open up a whole ton of possibilities further than those he listed. I don't know if I'm just misunderstanding something or if he really did miss some options. For instance if you flipped your piece into the unlisted 4th possible move and then moved the lower neutral coin into any position on the board then you can extend the game out at least one more move. I don't know why he left out the options that would extend the game. I also don't get why in situation B pink would intentionally move the neutral piece into a position that would cause him to lose the game and at the same time not show positions in A that would have pink move the neutral piece into an advantageous position. There is just a whole bunch wrong with those scenarios

Most of this video applies to all deterministic perfect information games, like chess, go, checkers, nine mens morris, tafl, connect 4 etc. (Although some of them can't go on forever). What makes this game special is that it strikes the balance where it's not obvious how to play correctly, but you can master it in a couple of days, where the other games can take a lifetime to master.

I was recently at a camp for the disabled and I played this with my cabin mate, we had lots of fun playing such a simple game, though we changed the rules so the penny could only move to open spaces connected to eachother and not boxed off areas
I like the fatal weak neutral & strong mindset. It really reflects how "just being reliable enough" can have you win through a competitor's mistake. Rarely need to play the risk because just not exposing yourself is already on the winning side. Only when both sides are in the skill level of not losing through mistakes, strong moves even start to matter. Man i love that.
Thanks for reading. The idea is: On an even playing field of experience, if you spend time only learning neutrals of playing it safe, you only need to focus on 1/3 rd of the game but win 99.5% of the time, constantly beating opponents who will make mistakes. Because the winning move is a ~1/200 chance for someone to unknowingly play to then develop into an unbeatable turn order. Only when both players mastered "not losing by mistake", the winning move even matters to learn because only then, weak moves are a guaranteed loss and only neutral moves eventually lose by chance (expecting a true neutral game to go on for a long time until one plays a winner by chance. (See chess, where low elosconstantly make mistakes and expose themselves, better elo ending in more draws and high elo confidently going for high risk moves, sacrificing high value pieces. Makes sense? More of a metaphor on how focusing on not making mistakes can put you ahead of ~99% Lmk if i'm completely wrong there

5:10 My guess: Nestle your L against Orange’s long end, and move the corner neutral one space inward. You will control half the board, the opponent’s L will be forced to flip, and Orange will have 3 edges along the side-a more vulnerable position as shown before. But I don’t know how they’d move the coins.

when this game first came out in the early 1960's, I had one...and I came across it in my backgammon game. It was always one of my favorite games.
I just played it for the first time, and came up with a simpler way to play it, and possibly even guarantee an infinite draw. Every corner square gets a score of 0. Every outside square that isn't a corner gets a score of 1. Every inside square gets a score of 2. Maximize your score with every move, then think about what neutral piece move would take away your opponent's highest score position, while not allowing him a higher score position by moving said neutral piece.
How do you make the pieces.
new rule: if you win its required to say “take the L”
The game is 3 rounds total, the player who loses takes one of the L's, and puts it on their forehead. There are only two L's in the game and at the 3rd loss, the winning player just does the "Take The L" on them.
No if u lose u have to take the l

1:44 my secret strategy to always win at battleship
I played this when my high school was on lockdown till 10pm. I won every match out of about 20. It was easy to figure out the end game states early on, and use rotations of those board states to make my friend take the L.
Now I'm curious about why your high school was on lockdown until 10pm.
@@General12th nearby shooting. Suspect at large. Incompetent police and school administration.
"The possibilities here are endless" No they're not. You said yourself, there's only 2296 possible board states ;)
Which funny enough makes this game ridiculously easy to solve even for humans. We can easily memorize 2296 positions and just play perfect every time.
@@Figgy20000 I'm a little hazy about whether that number is before, or after, taking various reflection and rotation symmetries into a account - but you're probably right, yes.
smh vsouce 2 i biased
@@Figgy20000 Most people won't memorize that many moves because it would take a lot of time. You'd better just play it a lot and get a feel for it. You'd end up categorizing the moves intuitively. I'd personnally just write an AI for it. Either specific to the game that just memorize for me all the positions. Or based on reinforcement learning, a method that would, by playing a lot, come up with an evaluation function that tells how strong a move is. This last one is my obsession of the last few month.
@@Ceelvain Rubix Cubers and top Chess GMs have easily memorized more positions than actually exist in this entire game. If someone were to throw a million dollar prize pool at this thing next Saturday I'd bet you we'd have at least 50 100% perfect human players entering that same weekend.

5:29 Counter-move B is invalid according to the rule that you can't move the neutral piece before the L-piece move is completed.
Yep, I noticed that while it was in scene as well...
It is valid. The pink player flipped his piece and then moved the neutral piece from 1x3 to 3x1. Then the orange player puts his orange piece to where the neutral piece was. That's also the only move where the pink player moved the neutral piece for some reason.
So he is saying that its the pink player that moved the coin? The pink player does his move in "my possible moves"
(I think)
@@pasijutaulietuviuesas9174 Pink did not move the neutral piece, look again. The finalized board after Pink's move, which was just an L-flip, shows no movement of the neutral piece. Unless Kevin made an error in setting it up, but either way it wouldn't make sense for pink to move the neutral to (3,1) anyway, it wouldn't benefit them. It's one of the fatal moves they could make.

There also is a "perfect clear setup", which gives you a not guaranteed, but high chance to get a perfect clear withing the first 10 (11 with the "hold" option) tetriminos.

It's actually quite interesting how much this just emphasises the 'control the centre square' philosophy of game shows! I would assume that the principle behind play is 'if you keep your L in the middle, you cannot lose - if you place your penny in the wrong spot, you can be moved out of the middle, so it requires TWO mistakes by player one to lose'.

4:53 Isn't the B countermove here illegal based on the rules explained before? Assuming pink didn't move the penny from the top row before orange's turn, orange should not have been able to place the L the way it did, because the penny can't be moved until after the L is moved.
