SiGameGen charges for one thing: a code model writing a version of your game. The first build of an idea is a version, and so is every change you ask for afterwards, because the model rewrites the whole game file each time. The price depends only on the tier you pick, never on how long or how complex the game turns out to be. The Build button shows the price before you press it, and the credits are reserved when the build starts and kept only if a finished game comes back.
Everything that happens after a build is free. You can replay the game as many times as you want, send the share link to friends, open it on a phone, download the single HTML file and host it yourself. Playing does not consume creation credits.
| Tier | Code model | Credits | Typical wait | Best for |
|---|---|---|---|---|
| Fast | DeepSeek V4 Flash | 9 | ~2 min | Arcade ideas, quick tweaks, trying many concepts |
| Pro | Kimi K2.7 Code | 45 | ~5 min | Bigger games: levels, bosses, menus, tighter controls |
Fast uses a quick general model with its reasoning switched off, so it writes the game straight away. It is ideal for one-screen arcade games and for small edits. Pro uses a model trained for programming that plans before it writes; it produces longer games with several levels, menus and smoother controls, and it follows long, detailed prompts more closely. Both run on Cloudflare, and both deliver one self-contained HTML file.
Most people build a game, play it, and then ask for a handful of changes. Counting one first build plus five rounds of edits:
In pack terms, the Starter pack (1,800 credits) covers 20 projects built the mixed way. Creator (5,000 credits) is enough for a game a day for a month with room to spare, and Studio (12,500 credits) suits teachers preparing a class set, game jams and studios testing many prototypes.
Here is how SI game generator pricing works out for the space shooter pictured above. The first version came from one Pro request, which costs 45 credits. Suppose you then ask for three changes on Fast: a bigger boss, a pause key and slower enemy bullets. That is 27 more credits, 72 in total, or about 200 cents on the Starter pack. If one of those changes is not what you wanted, you open the previous version and describe the change differently; the version you skipped costs nothing extra to keep.
Each build runs a large code model on Cloudflare’s GPUs, and the longest games use thousands of words of output. Each tier has a fixed credit price based on an estimated compute budget, which is why a short game and a long game cost the same. Storage for your versions, share links and the bandwidth when friends play your games are included. That keeps SI game generator pricing simple: one number per tier, shown on the button before you build.
Choose Starter for a focused project. Creator provides more room to iterate and fits anyone who builds every week. Studio has the lowest per-credit price among packs. With every option, the SI game generator pricing per build stays the same; a bigger pack gives a better per-credit rate in the same balance.
Credit packs suit occasional projects. Memberships suit regular creation, with a predictable monthly credit allowance. The annual option costs the same as ten monthly payments and releases its allowance in twelve monthly installments. Packs can supplement a membership without changing the renewal date. Availability is shown on each plan; preview plans cannot be purchased yet.
Every account created with Google gets 40 credits to try the SI game generator before paying anything. The gift center adds a welcome gift, a daily check-in with a seven-day streak bonus, a gift for your first game and credits for each friend who joins through your invite link. Free credits have no cash value, but they buy builds exactly like paid ones.
No. Credits are only used when the code model writes a new version. Playing, restarting, sharing the link and downloading the HTML file are free, as often as you like.
Membership plans are shown as previews until checkout is enabled. Monthly plans renew each month; yearly plans charge once a year and release credits monthly, not all at once. Credit packs remain one-time purchases.
Cancel future renewal from Wallet & assets. Released credits remain in your balance, and an annual plan continues its purchased monthly releases through the paid year. Refunds stop remaining releases. Monthly credits are included in the plan price and do not receive pack or first-purchase bonuses.
Nothing. If the model stops before the game is complete, does not return a complete HTML document or takes too long, the build is marked as failed and its credits go back to your balance automatically.
Yes, for every request. A common pattern is to build the first version on Pro and make small changes, such as colors or speed, on Fast.
A one-time $9.90 first-game pack offers 90 credits to eligible first-time buyers, once per account. Yearly memberships are priced at ten monthly payments for twelve monthly credit releases. New credit packs and memberships do not receive extra pack or first-purchase bonuses. Available gifts are shown in the gift center.
Packs are final because the credits arrive instantly, but failed builds are always returned in credits and payment mistakes such as a double charge are fixed on request. See the Refund Policy for details.

Product details and limitationsSiGameGen is most useful for small browser games and interactive prototypes. Complex multiplayer systems, platform certification, app-store publishing and production QA need additional engineering and review. A generated HTML file alone does not provide those services.
