Juragan Kos · game mockup v0.8
A cozy mobile game about running a boarding house (kos). Android first. These are static screen designs for Phase 1: what each screen shows, what the player can do, and the acceptance criteria. The kos itself is 3D in the game (see "Kos map 3D"); the other screens show the flat layout and states. All names and numbers are example data.
Core loop
Fill rooms → collect rent → handle tenants and events → build rooms and facilities on the grid → earn more rent → move to a bigger city
Screens
Changes in v0.8
| ID | Decision | Cost we accept |
|---|---|---|
| D29 | Rent is collected by tapping each room's coin bubble. No "Tagih semua" in free play. | More taps; that is the point (reason to open the game) |
| D30 | 1 in-game month = 1 real day (was ≈ 10 minutes). Each room fills hour by hour; a Rp500.000/month room makes about Rp20.800 an hour. Build and repair times stay as they are. | Slower economy; all prices need a tuning pass |
| D31 | Each room stores at most 8 hours of rent; 12 hours while the Kartu juragan is active. The Kartu juragan (Rp19.000 / 30 days, + 10 coins a day) moves to Phase 1. | Monthly subscription work in Phase 1 (CTO to confirm) |
| D32 | Caretaker (penjaga kos) moves to Phase 1: Lv 6, Rp2.000.000 to hire, keeps 10% of what they collect. Collects every room automatically, in play and away, within the same 8 / 12-hour storage. Other staff stay Phase 2. | Fewer taps for players who hire, so less pull to open the game |

|---|---|---|
| D28 | Mezanin is the fourth room size, after Besar: Kecil → Sedang → Besar → Mezanin, through "Perbesar". Needs a Besar room on the top floor. The bed moves to a loft, two slots open below (Area santai, Rak buku), base rent Rp700.000 → Rp850.000. Example: Rp15.000.000, Lv 13, 12 jam. Replaces D26 (mezzanine as a separate add-on). Comes with Besar in Phase 2. | No mezanin at launch; tile above it can't be built |
Changes in v0.6
| ID | Decision | Cost we accept |
|---|---|---|
| D24 | Selasar: a narrow paved walkway between neighbouring rooms on floor 1, and a railed corridor along the room fronts on floors 2–3 leading to the stairs. Automatic, free, takes no tile. | Plot looks a little less dense |
| D25 | Stairs stay small: at most about a third of a tile wide, inside the side of the plot, one flight per floor. | — |
| D26 | Replaced by D28. Mezzanine (F-12, P1): a loft for rooms with nothing above. Bed moves up, new "Area santai" slot below, +Rp150.000 base rent. The tile above is blocked while it exists. | Players must choose: more rent per room, or another room above |
| D27 | Neighbourhood: a minimarket, a warung makan and a bakso stall beside the kos, with people and motorbikes. Decoration only in Phase 1 (generic names, no real brands). Could give a "near food and shops" bonus in Phase 2. | Small extra art; no gameplay yet |
For the 3D prototype
- Stairs: about a third of a tile wide, one flight per floor, inside the plot edge (F-01.AC16).
- Selasar: paved strip in the gaps between floor-1 tiles; railed corridor in front of upper-floor rooms (F-01.AC15).
- Mezanin (D28): a room size, not an item. Loft with a small ladder appears when a Besar room on the top floor is enlarged to Mezanin; "Bawah / Mezanin" switch in the room view (F-12).
- Neighbours: low-poly minimarket, warung and bakso cart on the street side, generic signs, a few walking people and parked motorbikes (F-01.AC17). Keep within the draw-call budget.
Changes in v0.5

|---|---|---|
| D23 | One game screen, strategy-game style. The kos fills the phone; controls sit in the corners (same layout as the 3D prototype). Toko, Penghuni, Kabar and Kota open as floating menus; Bangun opens a bottom tray and places items on the map with a check / cross; room interior is a camera zoom. No feature opens another page. The old full-width top bar and bottom tab bar are removed. | Less room for long lists; menus must stay short |
Changes in v0.4
| ID | Decision | Cost we accept |
|---|---|---|
| D21 | No drawers. Tapping a room or facility shows round action buttons over the map; an action opens a small floating card (next to the room for info, centered for decisions). Every card has a close button. | One extra tap to reach details |
| D22 | Compact scale: one-row top bar, body text 13, buttons 38 px, smaller tiles and menu, so more of the kos is visible. | Small text on very small phones; check in the phone test |
Changes in v0.3
| ID | Decision | Cost we accept |
|---|---|---|
| D19 | Stairs are built automatically when the player adds floor 2 or 3. They run along the side of the building and take no tile. Replaces the stairs tile. | Stairs placement is no longer a player choice |
| D20 | New visual style: flat, simple, local. One green action color, line icons instead of emoji, initials instead of emoji faces, no shadows or gradients, plain Indonesian copy, prices written Rp10.000. See the design system. | Less playful look until real art arrives |
Changes in v0.2
| ID | Decision | Cost we accept |
|---|---|---|
| D14 | Room upgrades happen per item inside the room (F-11). Rent = room size + item upgrades. Replaces the fixed Standar → AC → Kamar mandi dalam → Premium ladder. | More taps per room; more item art |
| D15 | Making a room bigger happens inside its own tile (Kecil → Sedang → Besar). The room never takes a second map tile. | Less realistic; 2-tile suites could come later |
| D16 | Phase 1: sizes Kecil and Sedang, 5 slots, 3 levels each (15 items). Phase 2: Besar size, TV and decor slots, level 4, paid looks. | Fewer items at launch |
| D17 | If an upgrade pushes rent above the current tenant's budget, the player chooses: keep their old rent, or raise it and likely lose them. | One more decision screen |
| D18 | Items are bought only with in-game money. Gold coins buy speed-ups now and item looks (skins) in Phase 2. | Less gold spending on items |
Changes in v0.1
| ID | Decision | Cost we accept |
|---|---|---|
| D11 | Neighbor effects cut to one: a room touching a garden gets a happiness bonus. No noise or other penalties for now. | Less depth in where you build; can return later |
| D12 | Lowest price is Rp10.000 (starter pack and smallest coin pack). The Rp3.000 and Rp5.000 items are dropped. | Fewer very small first purchases |
| D13 | City 1 plot is 4×3 tiles, up to 3 floors (about 22–26 rooms when full since D19). | — |
Not in Phase 1
