Game Design: Roll to Move

I was watching some game design videos and how they complained about 'roll to move' and I just felt like, hang on, where they dissing it because they don't understand it? or just because everyone says that its bad?

Why and When Roll to Move is the correct way to go.

If we look at the mechanics of a roll to move, for example, we'll use a single d6. if both players tokens are standing at the beginning of a 6 spot track. then yes, roll to move is a poor mechanic. The likelyhood of one player rolling a 5 and the other a 1, means that neither player had any influence over the event and so its not fun. 

Sure, Odds are, the 2nd roll might be the opposite, and they both win. And yes, you can extrapolate out, if most people are playing a somewhat fair game, then over the course of 10 rolls, with a roll average of 3.5, the two players, on average will get to the finish line around the same time.

Here we have red, rolling poorly, and blue rolling well. Blue has a lead of 5 squares
Three turns Later, and Blue is even further ahead by 9 squares, so blue feels like he's winning.

Yes, If the Law of Averages comes in.. 
While Contrived, Blue and Red have 12 turns each, and arrive at the end, in the same round.

In such a game, going first, has higher odds of winning, because he's cross the line first.

Yet, there is no point to this.. regardless if you roll once or a hundred times.. you're not making any choices. So there is no game here, its just an exercise in dice and math, which is why its for kids.. to teach them dice and math, and that's all.

NEXT.. If we look at the squares themselves as opportunities.

In many games, a roll of a dice, gives you a table of opportunities, Lets say 1 to 6. You roll, consult the table, then I roll and consult the table. The table, and its choices are the game.


Roll Results
1Take a Coin
2Take a Shoe
3Take a Bag
4Take a stone
5Give an Item to another player
5Swap an Item with another player
Now this game is just about collecting objects, You take turns for a set number of turns, say 12, and you want to get a complete set of all 4 items, which earns you a point.

But it can be a little boring to just roll a d6, and look at a chart.. if instead the chart was on the table, like a board.. we can see it..

Hence why many roll and move games have the 'chart' as the next 6 steps you can land on:
Now we see that while red landed on a 2, and took a shoe, blue landed on a 6, and would need to swap an item (to ensure this works, we need rules about what happens if you can't give/swap)

In Blues Next roll, 1->6 will still equate directly to the chart, but for Red, the order has been mixed up, where a roll of a 1 will give them a score of 3. because there is no modification to the dice rolled, the odds are still the same. (see more below)

Now, we have 12 rolls, resulting on 12 checks on the chart, and the roll->move structure is actually just a timer for how long the game lasts for.

In essence, provided there is enough rounds.. 12 or more, statistically, most players are going to have a fairly even chance of getting each roll once, and as long as you design in the rule to allow some exchange with a player who didn't roll often enough, or rolled too much of, it balances out.

This actually is pretty much exactly how Catan works. just the 'movement' track is in your head, for how many plausible turns until you hit the end of the game.

Roll modifiers.


IF you could modify the roll made.. then we unlock a whole gamut of possibly interesting choices. Since the roll of a 1 in that second turn, equates to a 3 for red, if red had a +1 token that could be used. Red can choose either a bag or a stone as their 'gain' allowing them more strategic choices.

Conclusion

So, when we look at older games, and think, Oh, Roll and move, how wrong. We fail to realise some of the very complex decisions that are likely to have been made to ensure that the 'track' has equidistant effects and choices for players, to ensure a balanced end game.
