Low vs High Numbers: How Balanced Are Singapore TOTO Draws?大小号码：新加坡多多开奖有多平衡？
Split the 1–49 pool in half and count how many Winning Numbers land on each side — the results are more balanced than you might guess.
Defining Low and High
For this site's purposes, "low" numbers are 1 through 24, and "high" numbers are 25 through 49 — a near-even split of the 1–49 pool (24 low numbers, 25 high numbers). Every draw's 6 Winning Numbers fall into some mix of the two.
Counting Low and High Numbers in a Draw
Just like the odd/even split, a draw's low/high split can range from 6:0 (all low) through 3:3 (perfectly balanced) to 0:6 (all high), with every combination in between.
How the Splits Compare
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), here is how often each low:high split occurred:
- 3:3 (balanced) — 382 draws, 31.4%
- 2:4 — 316 draws, 26.0%
- 4:2 — 288 draws, 23.7%
- 5:1 — 106 draws, 8.7%
- 1:5 — 103 draws, 8.5%
- 0:6 (all high) — 14 draws, 1.2%
- 6:0 (all low) — 6 draws, 0.5%
Reading Balance, Not Predicting It
The 3:3 split is the single most common outcome, followed by 2:4 and 4:2 — draws with some mix of low and high numbers are, unsurprisingly, far more common than draws where all 6 numbers land on one side. All-low (6:0) and all-high (0:6) draws are both uncommon, matching the same underlying reason odd/even 6:0 and 0:6 splits are uncommon: there are simply many more possible combinations that mix both sides than combinations that don't.
What This Doesn't Mean
This describes what has happened, not what will happen next. Every 6-number combination — whatever its low/high split — has an equal chance of being drawn; the historical frequency of a particular split is not a signal about the next draw. This concept is related to Range Distribution on the Statistics page, which shows appearance frequency across five 10-number brackets rather than a simple low/high split.

把1–49号码池一分为二，数一数每期开奖号码分别落在哪一边——结果可能比你想象的更加平衡。
如何定义「小号」与「大号」？
在本站的统计口径中，「小号」指1至24，「大号」指25至49——这样划分后，1–49号码池被近似均分为两部分（24个小号，25个大号）。每一期开奖的6个开奖号码，都会以某种比例分布在这两部分之中。
如何统计一期开奖中的大小号码？
与单双比例类似，一期开奖的大小号比例，也可以从6:0（全为小号）、3:3（完全均衡），一直到0:6（全为大号），涵盖中间的各种组合。
各种比例的出现频率如何？
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），各种小号:大号比例出现的次数如下：
- 3:3（均衡）——382期，31.4%
- 2:4——316期，26.0%
- 4:2——288期，23.7%
- 5:1——106期，8.7%
- 1:5——103期，8.5%
- 0:6（全大号）——14期，1.2%
- 6:0（全小号）——6期，0.5%
这是一种「观察平衡」的方式，而非预测
3:3是单一最常见的比例，其次是2:4和4:2——小号与大号混合出现的开奖，明显比全部号码都落在一边的开奖更为常见，这并不意外。全小号（6:0）与全大号（0:6）都很少见，原因与单双比例中6:0、0:6少见的道理相同：能凑出「大小混合」的组合数量，本就远多于「全部落在一边」的组合数量。
这说明了什么，又不能说明什么
以上内容描述的是已经发生的情况，而非将要发生的情况。无论大小号比例如何，每一种6号码组合被开出的概率都是相同的——某种比例在历史上出现的频率，并不能作为下一期开奖的信号。这一概念与统计页面中的「区间分布」有关，不过区间分布展示的是号码在五个10号区间中的出现频率，而非简单的大小号比例。想了解观察同一批开奖的另外两个角度，可参阅《新加坡多多的开奖号码总和，通常是多少？》与《单双号码：新加坡多多开奖通常是什么样子？》，也可以直接查看统计页面。
