How Spread Out Are Singapore TOTO Winning Numbers?新加坡多多开奖号码的分布有多分散？
Subtract the smallest Winning Number from the largest and you get the "spread" — a simple way to see how clustered or scattered a draw is.
What Is "Spread"?
Spread, as used in this article, is the difference between the largest and smallest of a draw's 6 Winning Numbers. If a draw's numbers are 4, 15, 22, 29, 33, 41, the spread is 41 − 4 = 37. It is a simple way to describe how tightly clustered or how widely scattered a draw's numbers are, and it is a separate measure from the Range Distribution chart on the Statistics page, which instead tracks how often numbers fall into five 10-number brackets.
The Typical Range
Across the 1,215 official Singapore TOTO draws this site currently covers (draw #2995, 9 Oct 2014, through the latest draw, #4209, 17 Aug 2026), the average spread is 36.1 and the median is 37. Since the 1–49 pool spans 48 (49 − 1), the largest possible spread is 48, and the smallest theoretical spread — 6 consecutive numbers — is 5. In this dataset, the narrowest spread actually observed was 11, and the widest was 48 (i.e., a draw that included both 1 and 49).
Narrow vs Wide Spreads
Grouped into ranges, spreads of 31–40 were the most common (535 draws, 44.0%), followed by 41–48 (400 draws, 32.9%) and 21–30 (247 draws, 20.3%). A spread of 20 or less — meaning all 6 numbers packed into a fairly narrow band — happened in only 33 draws, about 2.7% of the dataset.
Why Extreme Spreads Are Less Common
A very narrow spread requires all 6 numbers to land close together, which only a small fraction of possible 6-number combinations do; a moderate-to-wide spread, by contrast, can be produced by a huge number of different combinations. That is the same basic combinatorial reason the Number Sum tends to cluster around the middle rather than the extremes — see What Is a Typical Winning Number Sum? for more on that.
What This Doesn't Mean
A wider or narrower spread is not "better" and does not affect your odds — every valid 6-number combination, whatever its spread, has exactly the same chance of being drawn. This is a description of the historical record, not a strategy.

用最大的开奖号码减去最小的开奖号码，就得到了「分散范围」——这是判断一期开奖号码是集中还是分散的一种简单方式。
什么是「分散范围」？
本文所说的「分散范围」，指的是一期开奖中6个开奖号码里最大值与最小值之差。例如某期开奖号码为4、15、22、29、33、41，分散范围即为41−4=37。这是判断一期开奖号码是集中还是分散的一种简单方式，与统计页面中的「区间分布」图表是两个不同的概念——「区间分布」统计的是号码落入五个10号区间的频率，而非最大最小值之差。
通常落在什么范围？
基于本站目前覆盖的1,215期官方新加坡多多开奖记录（从第2995期，2014年10月9日，至最新一期第4209期，2026年8月17日），平均分散范围为36.1，中位数为37。由于1–49号码池跨度为48（49−1），理论上最大的分散范围为48，而理论上最小的分散范围（即6个连续号码）为5。在本数据集中，实际观察到的最小分散范围为11，最大为48（即某期开奖同时开出了1和49）。
较窄与较宽的分散范围
按区间分组来看，31–40区间的分散范围最为常见（535期，44.0%），其次是41–48区间（400期，32.9%）和21–30区间（247期，20.3%）。分散范围在20以内——即6个号码全部集中在一个较窄区间内——的情况只出现过33次，约占数据集的2.7%。
为什么极端的分散范围较少见？
要形成很窄的分散范围，需要6个号码都聚集在很接近的位置，而符合这一条件的六号码组合只占很小一部分；相比之下，中等偏宽的分散范围，则可以由数量庞大得多的不同组合形成。这与号码总和更容易集中在中间值、而非极端值附近，背后是同一个基本的组合学原因——详见《新加坡多多的开奖号码总和，通常是多少？》。
这说明了什么，又不能说明什么
分散范围较宽或较窄都谈不上「更好」，也不会影响中奖概率——无论分散范围如何，每一种合法的6号码组合被开出的概率都完全相同。以上内容只是对历史记录的描述，而非一种策略。想了解观察号码排列方式的其他角度，可参阅《新加坡多多开奖中，连续号码常见吗？》与《大小号码：新加坡多多开奖有多平衡？》，也可以在统计页面查看最新数据。
