Players can first select the total number of players that are in their group. TeeUp will provide them a list of different games which will work with the total number of players.
Players may also choose a custom game or customize the pre-set game chosen.
These define how players or teams are scored. There are 3 primary scoring formats however some games can have a combination of these styles within a match:
These define how players or teams play their ball:
These define the format in which the players or teams are matched up.

TeeUp will need to utilize the following data sets:
-
Database storing each golf game, including the rules, scoring, player criteria. -This may be a custom database I create -There will need to be flags on each golf game, primarily for number of players allowed. This way when a user indicates the total players, it will only display the appropriate games that meet the criteria
-
User Database
- This will be have components of an interactive social application where users can create profiles and add other users and create groups
-
Course Database - Will need to store the following:
- Course Names and Locations
- Course Score Card - So users can input scores in the application and have it align with the holes of the course
- Course Rating - USGA Course Rating is an evaluation of the difficulty of a golf course for scratch golfers. (More specifically, the number is an estimate of the average scores of the best 50-percent of rounds played by scratch golfers at the course being rated.) Course rating is very easy to understand because it is expressed in strokes. A par-72 course that is easy might have a course rating of 68.9; one that is difficult might have a course rating of 74.5. That means that a scratch golfer should be expected to average 68.9 strokes in his better rounds at the easier course; and 74.5 at the more difficult one.
- Course Slope Rating - The slope rating of a golf course is a measurement of it's relative difficulty for a bogey golfer compared to a scratch golfer. This value ranges from 55 (least difficult) to 155 (most difficult)
To put it another way: USGA Course Rating tells the best golfers how hard a golf course actually plays; USGA Slope Rating indicates how much harder the course plays for "regular" (meaning not among the best) golfers.

A USGA Handicap Index is a numerical value that represents a golfer's demonstrated playing ability, calculated based on their past scores relative to the difficulty of the courses and tees played, essentially providing a portable measure of how well a golfer plays across different courses; it is the official term used by the United States Golf Association to describe a golfer's handicap.
It is calculated by averaging the best 8 "Score Differentials" from a golfer's most recent 20 rounds, taking into account the course difficulty and playing conditions.
The Handicap Index allows golfers to compete fairly against others, regardless of the course they are playing on
Through the USGA handicap system, players can enter their USGA handicap (A further iteration may be able to API that data in from USGA)
The handicap scoring algorithm will then be applied to different games to ensure the proper number of strokes, points and other scoring is fairly integrated.
The handicap for a player for a given match is not only based on their actual handicap value, but also with the course rating. If a player is a 10 handicap, and they are playing a tougher golf course, their course handicap may actually be 13.
This will be an optional tool for players to apply when they play a game.
To convert a player's Handicap Index into a Course Handicap for a specific course and set of tees, use this formula:
Course Handicap = (Handicap Index) × (Slope Rating ÷ 113) + (Course Rating - Par)
Explanation of Terms
Handicap Index: A portable number representing your potential scoring ability (e.g., 10.4)
Slope Rating: How difficult the course is for a bogey golfer compared to a scratch golfer (range: 55–155; 113 is average)
Course Rating: What a scratch golfer is expected to shoot (e.g., 71.2)
Par: The expected score for the course (e.g., 72)
Say a golfer has a Handicap Index of 12.3, and they're playing from a tee with:
Slope Rating: 130 Course Rating: 70.5 Par: 72
Course Handicap = 12.3 × (130 / 113) + (70.5 - 72) = 12.3 × 1.1504 + (-1.5) = 14.15 - 1.5 = 12.65 → Rounded = 13
So this player’s Course Handicap = 13.
Once a player(s) handicap for a match is calculated, in stroke play, it is fairly simple to determine the handicap for scoring the match.
Each hole on every golf course is assigned a difficulty value ranging from 1-18, 1 being the "hardest" and 18 being the "easiest" (assuming it's a standard 18 hole course).
If a player has a handicap of 7 for a given match, they will, as a result, receive an additional stroke on the 7 most difficult holes.
There will be 2 scores for any player using a handicap in their match
GROSS SCORE: This is the score (in stroke play) the player receives without factoring in the handicap.
NET SCORE: This is the score (in stroke play) the player receives once the handicap is factored into the score.
E.g. Assume a player has a handicap of 7 for a given match. They are playing the 2nd hole which happens to be the #1 handicap hole on the course (meaning it's considered the most difficult hole on the course). This 2nd hole that this player is playing is a Par 5. Now assume this player scores a 6 on this hole meaning it took them 6 strokes to get the ball in the hole. Because this is the #1 most difficult hole on the course AND the player has a handicap of 7, then they will receive a Net Par of 5 when the hole is scored.
In some formats (e.g., Best Ball, Scramble, Match Play), you apply allowances to the Course Handicap to get the Playing Handicap:
So:
Playing Handicap = Course Handicap × Format Allowance %
📄 Setup
Assume:
A2: Handicap Index (e.g., 12.3) B2: Slope Rating (e.g., 130) C2: Course Rating (e.g., 70.5) D2: Course Par (e.g., 72) E2: Allowance % (e.g., 0.85 for 85%)
function calculateCourseHandicap(handicapIndex: number, slope: number, courseRating: number, par: number): number { const rawHandicap = handicapIndex * (slope / 113) + (courseRating - par); return Math.round(rawHandicap); }
function calculatePlayingHandicap(handicapIndex: number, slope: number, courseRating: number, par: number, allowancePercent: number): number { const courseHandicap = calculateCourseHandicap(handicapIndex, slope, courseRating, par); return Math.round(courseHandicap * allowancePercent); }
// Example const courseHcp = calculateCourseHandicap(12.3, 130, 70.5, 72); // => 13 const playingHcp = calculatePlayingHandicap(12.3, 130, 70.5, 72, 0.85); // => 11
def calculate_course_handicap(handicap_index, slope_rating, course_rating, par): raw_handicap = handicap_index * (slope_rating / 113) + (course_rating - par) return round(raw_handicap)
def calculate_playing_handicap(handicap_index, slope_rating, course_rating, par, allowance_percent): course_handicap = calculate_course_handicap(handicap_index, slope_rating, course_rating, par) return round(course_handicap * allowance_percent)
Example: course_hcp = calculate_course_handicap(12.3, 130, 70.5, 72) # => 13 playing_hcp = calculate_playing_handicap(12.3, 130, 70.5, 72, 0.85) # => 11

- There will be a description of the game as well as the rules of the game selected
- Once selected, users can make certain modifications to the game (will have to limit the types of modifications to ensure the rules of the game or automatic scoring isn't impacted)
- If the user selects "Custom Game" they will need to input certain criteria such as (scoring stlye: stroke play, match play, hybrid) and determine other rules.
- Wagering - If the group wants to wager money, they can determine the wager amounts, pot, so TeeUp can track and score the winnings properly.
-
Match Preview: Once game selection has been made, users will see a Match Preview. This preview will display an overview of the match, which holes certain players have strokes on (per the handicap indexes), and the stakes. This is generated prior to selecting "Begin Match" to account for any edits or changes that need to be made.
-
Start Match - (There will have to a unique match ID or other identifier which will allow users on different networks to be part of the same match).
This section of the application will provide detailed descriptions and rules of the different games.
