What "house" and "ending" mean, and how players use them.
Every teer result is two digits. The house is the first digit (0–9) and the ending is the last digit (0–9). A result of 47 means house 4, ending 7. Players track which houses and endings appear most often — our common numbers page shows the hottest first and last digits per game, counted from real announced results.
Take the last 60 announced results of a game, split each number into its two digits, and count. The most frequent first digits are the "hot houses"; the most frequent last digits are the "hot endings". That's all there is to it — descriptive statistics, not a prediction system.
