How to Host and Enter Tetramon Tournaments
Version note: These steps cover the Windows PC 1.0 interface through Build 1.02. Console buttons and later balance changes may differ.
A prize tournament can turn your tidy card shop into a packed local venue in one morning. It can also fill every play table while the checkout line curls around a booster shelf. The shop does not pause while you duel, so stock, queues, wages, and the occasional fragrant customer still need attention.
Unlock the furniture and playable deck
| Requirement | How to unlock | Build 1.02 cost or capacity |
|---|---|---|
| Play Table | Shop Level 2 | $200; seats two entrants |
| Workbench | Shop Level 7 | $1,000; used to build and select a deck |
| Active Tetramon deck | Create it at the Workbench | Exactly 50 cards, then select Use |
| Tournament Prize Shelf | Shop Level 25 in MY DIY | $5,000 |
The smallest supported tournament has eight entrants, so it needs four numbered Play Tables. A 32-person event needs sixteen. Leave a usable path to both chairs and open space in front of the Tournament Prize Shelf. Otherwise, your big event can become the Tetramon version of lost luggage.
If you own none of the furniture, the minimum hosting setup is $5,800 for the prize shelf and four basic tables. Add the $1,000 Workbench if you also want to enter and have not bought it yet. There is no separate tournament-hosting fee on the Build 1.02 setup screen, but prize stock, wages, bills, and lost normal table income are still real costs.
Do not confuse the two event menus. Manage Events controls ordinary table formats and their hourly fee. Prize tournaments use the separate Tournament app and Tournament Prize Shelf. Tournament competitors occupy their assigned tables instead of paying the normal hourly table rate.
Run the pre-event check before registration
- Restock the packs, boxes, sleeves, and deck boxes that sell fastest.
- Keep enough operating cash for the next stock order, wages, bills, and any paid regular event charge.
- Clean the floor and refill scent machines near the entrance, tables, and register.
- Cover checkout and restocking with workers if payroll allows. If you only have one worker, protect the register first.
- Open the Workbench, confirm that the deck contains exactly 50 cards, and select it as the deck in use.
- Interact with every tournament table and assign a number manually or with Auto.
- Place the Tournament Prize Shelf on the shop floor with clear space in front of it.
- Load only prizes you are willing to lose. Do not put your favorite slab on the shelf and then discover that your deck has the structural strength of wet cardboard.
Open registration in this order
- Buy and place the Tournament Prize Shelf from MY DIY.
- Stock its prize slots with items accepted by the shelf and tournament setup menu, such as singles or sealed card products.
- Interact with the shelf screen or open the phone's Tournament app.
- Assign prizes to the available 1st, 2nd, 3rd, and Top 8 tiers. Make sure the shelf holds every copy the menu requires.
- Choose a participant count shown between eight and 32. Provide one numbered Play Table for every two entrants.
- Set the entry fee. The menu shows the prize value and a suggested fee, but you can change it. A steep fee may leave registration open for several days.
- Select Start Registration.
- If you want to compete, use the tournament page's Join option while registration is open. In Build 1.02, your shopkeeper's slot does not pay the entry fee.
NPC customers fill the remaining slots. Once every slot is taken, the tournament starts automatically on the next in-game day after you open the shop; there is no second manual start button. For profit estimates, count entry fee × paid NPC check-ins. Do not multiply by the full field when your free player slot is included.
Find each opponent and complete every round
- Open the shop on tournament day. Entrants check in, pay, and move toward their numbered tables.
- Read the live pairing screen on the Tournament Prize Shelf. It shows the current round, matchup information, table assignments, and standings.
- Go to your assigned table and approach the waiting tournament opponent. Start the duel with right mouse button on PC or the gamepad's right face button.
- After the match, return to the pairing screen. Wait for the next round to post, then note your new opponent and table number.
- Repeat until the scheduled rounds finish. The other matches resolve around the shop while you play.
This is standings-based round play, not a simple single-elimination bracket. A win improves your record, while one loss does not automatically remove you from later rounds. Final rank can also use the displayed tie-break statistics, including opponent match-win percentages. That means a strong record helps, but it does not guarantee first place or a particular prize.
If your pairing is posted but the duel prompt is missing, check that the assigned table is numbered, the opponent is waiting alone, and your active deck still has 50 cards. Build 1.01 fixed a case where an unstarted player match could not be joined, and Build 1.02 added a tournament-progression fix. Update the game before rebuilding the whole shop in a burst of retail despair.
Know what wins, losses, and placement pay
- Entry income: Paid NPC entrants hand over the chosen fee when they check in. Your own Build 1.02 entry does not add another fee payment.
- Wins and losses: Results change your tournament record and final standing. A loss hurts placement but does not automatically end your event after one round.
- Placement prizes: The final ranking decides which assigned tier you receive. If your shopkeeper finishes in a prize position, you keep that tier's items. Entrants in the other prize positions collect their assigned stock.
- Shop XP: Completed tournament table play can add shop experience, but the setup menu does not promise a fixed XP payment for first, second, or any other placement. Compare the XP bar before and after the event instead of budgeting around one universal number.
- Gift packs: Winning a player-controlled duel can produce a customer gift pack. Build 1.02 raises the chance that a win gives an Ascension Card Pack even at lower shop levels, but that pack type is not guaranteed.
Keep the retail floor alive while you duel
A Tetramon match takes several minutes, and the rest of the shop keeps moving. Regular shoppers can still empty shelves and build a checkout queue while tournament entrants occupy the numbered tables. Those tournament matches also replace the ordinary hourly income those tables could have earned. For a large field, put a worker on checkout, keep restock routes clear, and avoid starting your match while the register is already flashing distress signals.
Check whether the tournament actually paid
First calculate the direct event margin: NPC entry fees − replacement cost of awarded prizes − extra payroll − any regular event charge paid that day. Then compare the full day's profit with a similar non-tournament day. Include the normal table fees and retail profit you missed while the tournament used the floor.
If queues stalled or shelves stayed empty, try an eight-person event with four tables placed away from the register. If registration crawled, lower the fee before raising the prize pool. If the event drained tomorrow's stock money, pause tournaments, switch ordinary tables back to the free Standard format, and rebuild dependable inventory. Tournaments are a lively side engine; the shelves still pay the rent.
