Odd vs Even: What Do Singapore TOTO Draws Usually Look Like?单双号码：新加坡多多开奖通常是什么样子？
Every draw splits into some mix of odd and even numbers — from perfectly balanced 3:3 to the rare 6:0. Here is what actually happens.
Counting Odd and Even Numbers in a Draw
Every one of the 6 Winning Numbers is either odd or even, so every draw has an odd:even split — 3 odd and 3 even (written 3:3), 4 odd and 2 even (4:2), and so on. This is one of the patterns shown in this site's Statistics page under Pattern Snapshot.
The Full Range of Splits
There are seven possible splits: 6:0, 5:1, 4:2, 3:3, 2:4, 1:5 and 0:6. The first number is always the odd count, the second the even count, so 5:1 means 5 odd numbers and 1 even number, while 1:5 means the reverse.
Which Splits Are More Common
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 split occurred:
- 3:3 (perfectly balanced) — 437 draws, 36.0%
- 4:2 — 288 draws, 23.7%
- 2:4 — 281 draws, 23.1%
- 1:5 — 96 draws, 7.9%
- 5:1 — 93 draws, 7.7%
- 6:0 (all odd) — 10 draws, 0.8%
- 0:6 (all even) — 10 draws, 0.8%
Why 6:0 and 0:6 Are Rare
All-odd (6:0) and all-even (0:6) draws are the least common outcome — each happened only 10 times in this entire dataset, about 0.8% of draws. That is expected, not unusual: the 1–49 pool has 25 odd numbers and 24 even numbers, so there are far more ways to pick a mixed combination (some odd, some even) than to pick 6 numbers that are all one or the other. A balanced-looking split like 3:3 or 4:2 simply has many more possible combinations behind it.
What This Doesn't Mean
None of this predicts the next draw. Every valid combination of 6 numbers — whatever its odd/even split — has the same chance of being drawn; the historical frequency of a split only describes how often it has happened, not how likely it is to happen again.

每一期开奖都会呈现某种单双号码组合——从最均衡的3:3，到极为罕见的6:0。真实情况究竟如何？
如何统计一期开奖中的单双号码？
6个开奖号码中的每一个，不是单数就是双数，因此每一期开奖都会形成一个单双比例——3个单数、3个双数（记作3:3），4个单数、2个双数（4:2），以此类推。这是本站统计页面「规律速览」中展示的规律之一。
一共有哪些可能的组合？
一共有七种可能的单双比例：6:0、5:1、4:2、3:3、2:4、1:5、0:6。第一个数字始终代表单数个数，第二个代表双数个数，因此5:1表示5个单数、1个双数，1:5则相反。
哪种组合更常见？
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），各种组合出现的次数如下：
- 3:3（完全均衡）——437期，36.0%
- 4:2——288期，23.7%
- 2:4——281期，23.1%
- 1:5——96期，7.9%
- 5:1——93期，7.7%
- 6:0（全单数）——10期，0.8%
- 0:6（全双数）——10期，0.8%
为什么6:0和0:6如此罕见？
全单数（6:0）和全双数（0:6）是最少见的结果——在整个数据集中，两者各自只出现过10次，约占0.8%。这在意料之中，并不奇怪：1–49号码池中有25个单数、24个双数，因此能凑出「单双混合」组合的方式，远比凑出「全单」或「全双」组合的方式多得多。像3:3或4:2这样看起来更均衡的比例，背后对应的可能组合数量本就更多。
这说明了什么，又不能说明什么
以上内容都无法预测下一期开奖。无论单双比例如何，每一种合法的6号码组合被开出的概率都是相同的——某种单双比例在历史上出现的频率，只能说明它「已经发生过多少次」，并不能说明它「下次发生的可能性有多大」。想了解与开奖组成相关的其他角度，可参阅《新加坡多多的开奖号码总和，通常是多少？》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。
