Add-on

What is an Add-on?

Add-on，中文通常稱為增購、加購籌碼、附加籌碼，It means玩家在賽事指定時間點支付額外費用，獲得額外比賽籌碼並加入原有 Stack

The core of an Add-on is buying additional chips while retaining your existing chips.

When is an Add-on usually available?

Add-on 常見時間包括 Rebuy Period 結束時、第一次休息期間、Late Registration 結束時、指定盲注級別結束後，完成 Add-on 後，賽事通常會進入不能再購買籌碼的正式淘汰階段

An Add-on is often the final opportunity to purchase additional chips before a tournament moves from the rebuy stage into the Freezeout stage.

Who can purchase an Add-on?

不同賽事規則可能不同，常見資格包括：
→ 仍然留在比賽中的所有玩家
→ Players who completed registration before the designated time
→ Players who have not been eliminated
→ Players who meet specified chip restrictions

Most Add-ons do not require a player to be out of chips. Even players with a large Stack may be able to purchase one.

Add-on eligibility is usually determined by whether a player remains in the tournament, rather than by whether their chip stack is low.

The difference between an Add-on and a Rebuy

Add-on:
→ 通常在固定時間點開放
→ Most remaining players can purchase one
→ Usually does not require a player to be out of chips
→ Purchased chips are added directly to the existing Stack

Rebuy:
→ 通常發生於 Rebuy Period 內
→ May require a player to be out of chips or below a specified amount
→ Can be made multiple times during the rebuy stage
→ Primarily used to restore or replenish chips

A Rebuy is usually a conditional chip replenishment; an Add-on is an opportunity to purchase extra chips at a designated time.

The difference between an Add-on and a Re-entry

Add-on:
→ 玩家仍在比賽中
→ Elimination is not required
→ No new Entry is created
→ The player retains their original seat and chips

Re-entry:
→ 玩家先被淘汰
→ The player pays the full Buy-in again
→ A new Entry is created
→ The player receives a new starting stack

An Add-on purchases additional chips for an existing entry; a Re-entry creates a new entry.

The difference between an Add-on and a Freezeout

純 Freezeout 通常不允許 Rebuy、Re-entry、Add-on

If a tournament allows players to purchase additional chips at a designated time, it does not qualify as a pure Freezeout under the strictest definition.

不過 Add-on 結束後，比賽通常會轉為 Freezeout Structure

After the Add-on period, players generally cannot replenish their chips, and reaching zero chips results in formal elimination.

How is the Add-on cost calculated?

Add-on 費用由賽事主辦方設定，可能是與初始 Buy-in 相同、低於初始 Buy-in、高於一次 Rebuy、與 Rebuy 相同，For example：
→ 初始 Buy-in：$20
→ Rebuy: $20
→ Add-on: $20

However, the number of chips received for each may be completely different.

When assessing the value of an Add-on, do not compare prices alone; also compare the actual number of chips received.

How do you calculate the cost per chip?

You can use:Cost per chip = Add-on cost ÷ number of chips received

For example：
→ 初始 Buy-in 為 $20，獲得 10,000 籌碼
→ The Add-on is $20 and provides 20,000 chips

This means the Add-on's cost per chip is only half that of the initial Buy-in.

If an Add-on provides more chips for the same price, it will generally offer better value.

Is an Add-on always worth purchasing?

That's not necessarily true.是否值得需要考慮：
→ Add-on 費用
→ Number of chips received
→ Current blinds
→ Number of BB after the Add-on
→ Current average Stack
→ Your current chip stack
→ Tournament prize pool
→ Your total budget

The value of an Add-on comes from the future tournament EV generated by the additional chips, rather than simply increasing the number of chips in your stack.

When is an Add-on generally more valuable?

An Add-on is generally more valuable in the following situations:
→ 籌碼價格明顯低於初始 Buy-in
→ It provides a large number of BB
→ Your Stack is short
→ Tournament opponents are weaker
→ The prize pool has an Overlay
→ The added chips clearly increase your room to maneuver
→ The total investment remains within your Bankroll plan

If an Add-on turns a short stack into a playable Stack, it can generally increase future strategic options significantly.

When can you skip an Add-on?

Situations in which purchasing may not be appropriate include:
→ Add-on 價格過高
→ It provides too few chips
→ You would still be extremely short after purchasing it
→ It exceeds your planned budget
→ The opponents are very strong
→ You cannot stay to complete the tournament
→ You are unwilling to stop simply because you have already invested a lot

Do not automatically purchase an Add-on due to Sunk Cost simply because you have already made an initial Buy-in or Rebuy.

Should big stacks also purchase an Add-on?

大籌碼玩家仍可能適合購買 Add-on，The reason is籌碼仍有賽事價值、額外籌碼可增加施壓能力、能降低一次大底池失敗後的風險、有利於保持 Chip Leader 優勢，但籌碼具有遞減獎金價值，因此不能只認為籌碼越多就一定越值得

Whether a large Stack should purchase an Add-on still requires comparing the chip cost with the marginal value provided by the added chips.

Do short stacks need an Add-on more?

短籌碼通常更能直接感受到 Add-on 的效果，例如可以從：
→ 5BB 增加至 20BB
→ 8BB to 25BB

This increases:
→ Fold Equity
→ Opening options
→ 3-Bet Jam opportunities
→ Postflop playability
→ Time to wait for better situations

If an Add-on moves a player from a passive Push/Fold state back to a playable Stack, it generally has clear strategic value.

Does an Add-on increase the prize pool?

通常會，Add-on 收入可能全部或部分加入 Prize Pool

因此購買 Add-on 的玩家越多，最終獎池通常越大，但部分金額可能包含 Tournament Fee

Before entering, players should check how much of the Add-on cost goes into the prize pool and whether additional fees are charged.

How does an Add-on affect the average stack?

After many players purchase Add-ons:
→ 比賽總籌碼增加
→ The average Stack rises
→ The standard for a short stack changes
→ Effective stacks are redistributed

If you do not purchase one, your chips may become shorter relative to the overall field even if your actual stack has not decreased.

An Add-on decision affects not only your absolute chip count, but also your position relative to the average Stack.

How does strategy change after the Add-on ends?

Add-on 結束後，賽事通常不能再購買籌碼，策略應開始重視：
→ 淘汰的最終性
→ New effective stacks
→ Average Stack
→ Push/Fold
→ Distance to the Bubble
→ ICM

After the Add-on ends, the early-stage mentality of being able to replenish after losing will generally start to disappear.

Which data should be reassessed after an Add-on?

You should reassess:
→ 自己的 BB 數量
→ The largest Stack at the table
→ The shortest Stack at the table
→ Average chips
→ Effective stacks
→ Distance to the money
→ Whether opponents have tightened their Range

An Add-on changes the overall chip distribution, so you cannot continue using pre-Add-on Stack assessments.

Add-ons and Chip EV

購買 Add-on 等於使用真實資金換取比賽籌碼，需要評估：
→ 新增籌碼能創造多少未來 Chip EV
→ How much prize equity those chips can convert into
→ Whether the price is below the chips' fair tournament value

Because tournament chips cannot be directly converted into cash, they cannot be judged solely by their face value.

An Add-on is a tournament investment decision, not merely a simple purchase of more chips.

Add-ons and ICM

Add-on 通常發生在距離獎金圈仍有一段距離的階段，此時 ICM 影響可能有限，但如果賽事參賽人數較少、已接近 Bubble、獎金結構較平坦、Add-on 時間較晚，便需要更重視籌碼對應的獎金價值

Add-on value is mainly determined by price and the tournament value of chips, while the impact of ICM depends on the current tournament stage.

Add-ons and Bankroll Management

When entering a tournament with an Add-on, the following costs should be included in the budget:
→ Initial Buy-in
→ Potential Rebuy
→ Planned Add-on
→ Tournament Fee

例如賽事標示 $20 Buy-in，但若計畫使用一次 Rebuy、一次 Add-on，實際預算可能接近 $60 加相關費用

When evaluating your Bankroll, use your projected total investment rather than looking only at the initial Buy-in displayed on the main page.

Advantages of Add-ons

The main advantages of an Add-on include:
→ 增加比賽籌碼
→ Higher effective BB
→ More room to maneuver
→ Greater Fold Equity
→ Less short-stack pressure
→ Potentially lower cost per chip
→ A larger tournament prize pool

A high-value Add-on can allow players to improve their overall tournament competitiveness at a lower cost.

Disadvantages of Add-ons

The main disadvantages of an Add-on include:
→ 增加總投入成本
→ It can easily cause players to exceed their budget
→ It may be influenced by herd mentality
→ It may not offer a reasonable chip price
→ Increased tournament Variance
→ It can be confused with money already invested

An Add-on provides more chips, but it also increases real-money risk.

Practical example 1: A high-value Add-on

初始 Buy-in：$20，獲得 10,000 籌碼

Add-on:$20，獲得 30,000 籌碼

The Add-on costs the same price but provides three times as many chips.

If there is still sufficient room to maneuver after purchasing the Add-on, it will generally be highly valuable.

When an Add-on has a clearly lower cost per chip, purchasing it is often a reasonable choice.

Practical example 2: A short-stack Add-on

Add-on 前，你只有 6BB

增購後可以增加至 24BB

This moves you from a pure Push/Fold state and gives you:
→ Small Open
→ 3-Bet Jams
→ Flop play
→ More room to wait

An Add-on that clearly changes the level of your stack strategy generally has important strategic value.

Practical example 3: A big-stack Add-on

你已經是 Chip Leader，持有 100,000 籌碼，Add-on 可以增加 20,000 籌碼，此時應比較：
→ 20,000 籌碼的成本
→ Its marginal impact on a large Stack
→ Whether it can preserve a coverage advantage over other players
→ Whether the total budget is reasonable

Big stacks can still purchase an Add-on, but the marginal benefit of the additional chips may be lower than it is for short-stack players.

Practical example 4: An Add-on that is not worthwhile

The Add-on costs the same as the initial Buy-in but provides only a small number of chips.

按照當前盲注計算，這些籌碼只相當於 3BB

If the tournament opponents are very strong and the purchase already exceeds your investment plan, you can choose not to buy it.

Adding chips does not necessarily add sufficient tournament EV; you must compare the actual BB received with the cost.

Practical example 5: Reassessing opponents after an Add-on

During the rebuy stage, one player frequently goes All-in with weak hands.

After the Add-on ends, all players can no longer replenish their chips.

At this point, you cannot assume that the opponent will continue using the same wide Range, because elimination has become permanent.

Once the structure enters the Freezeout stage, you should reassess whether opponents have adjusted their aggression and calling frequency.

The most common beginner misconception

Many players believe Add-on 就是籌碼輸光後重新買入，In fact,Add-on 通常發生在固定時間，而且玩家不需要籌碼歸零；輸光後補充籌碼通常更接近 Rebuy

An Add-on is an extra purchase at a designated time, not a restoration of chips after elimination.

Another common misconception

Many players believe只有短籌碼玩家才需要 Add-on，In fact,只要籌碼價格合理，大籌碼也可能透過增購保持覆蓋優勢與戰略彈性

The value of an Add-on depends on its price and the function of the chips, not solely on whether the current Stack is short.

The third common misconception

Many players believe其他玩家都購買 Add-on，自己也一定要購買，In fact,每位玩家的 Bankroll、現有 Stack、時間安排與賽事優勢不同，不能只根據從眾心理決策

An Add-on should be decided based on personal EV and bankroll planning, not out of fear of falling behind.

What should you confirm before entering an event with an Add-on?

You should confirm:
→ Add-on 費用
→ How many chips can be obtained
→ When the Add-on is available
→ Who is eligible to purchase it
→ Whether it can only be purchased once
→ Whether an additional Fee is charged
→ Whether the Add-on amount goes into the prize pool
→ How many BB it represents after purchasing
→ Your maximum total budget

Only by understanding the complete rules can you correctly assess an Add-on’s true value.

How should you evaluate an Add-on decision?

You can consider the following in order:
→ Add-on 需要支付多少？
→ How many chips do you receive?
→ What is the cost per unit of chips?
→ How many BB will you have after purchasing?
→ How far is your current Stack from the average Stack?
→ Are the opponents in the field weaker?
→ Does the Add-on increase the prize pool?
→ Is it still within your planned Bankroll?
→ How much will your relative chip stack decline if you do not purchase it?
→ Are you being influenced by Sunk Cost or herd mentality?

A sound Add-on decision requires analyzing the price, chip value, tournament environment, and your financial capacity at the same time.

Key Takeaways

An Add-on is a mechanism that allows players, at a designated time in a tournament, to pay an additional fee to purchase more tournament chips and add them to their existing Stack.

Understanding Add-on, Rebuy, Re-entry, Freezeout, Rebuy Period, Chip Value, Average Stack, Chip EV, ICM, and Bankroll Management will help players correctly determine whether purchasing additional chips is worthwhile. An Add-on should not be decided based on herd mentality or money already invested; instead, players should compare the cost, number of chips, current blinds, relative Stack, and the future tournament EV that the added chips can generate.
