SiGameGenHow SI game generator pricing works
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 anywhere. There are no per-play fees, no bandwidth charges and no limits on how many people play a game you shared.
Fast and Pro: what you get for the credits
| Tier | Code model | Credits | Typical wait | Best for |
|---|---|---|---|---|
| Fast | DeepSeek V4 Flash | 18 | ~2 min | Arcade ideas, quick tweaks, trying many concepts |
| Pro | Kimi K2.7 Code | 89 | ~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.
What a whole game project costs
Most people build a game, play it, and then ask for a handful of changes. Counting one first build plus five rounds of edits:
- All on Fast: 108 credits, about 97 cents on the Starter pack.
- Pro build, Fast edits: 179 credits — the best value for most ideas.
- All on Pro: 534 credits, for games where every round needs the stronger model.
In pack terms, the Starter pack (1,100 credits) covers 6 projects built the mixed way. Creator (3,600 credits) is enough for a game a day for a month with room to spare, and Studio (10,400 credits) suits teachers preparing a class set, game jams and studios testing many prototypes.
An example project, step by step
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 89 credits. Suppose you then ask for three changes on Fast: a bigger boss, a pause key and slower enemy bullets. That is 54 more credits, 143 in total, or about 129 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.
Where the price comes from
Each build runs a large code model on Cloudflare’s GPUs, and the longest games use thousands of words of output. We price every tier so that a single build covers the model’s cost even for the biggest game it can write, 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.
Which pack should I buy?
Choose Starter to try both tiers and learn what makes a good game prompt. Creator adds 20% bonus credits and fits anyone who builds every week. Studio adds 30% and is the cheapest per credit. With every option, the SI game generator pricing per build stays the same; a bigger pack just adds bonus credits to the same balance.
SI game generator pricing compared with subscriptions
Many game makers and coding assistants sell a monthly plan with a message allowance that resets every month. That suits daily users, but most game ideas arrive in bursts: a weekend jam, a lesson plan, a birthday surprise for a friend. Paying per build means a quiet month costs nothing and a busy one is covered by a bigger pack. There is nothing to cancel, no renewal email and no surprise charge.
How to spend fewer credits
- Write the whole idea in the first prompt: controls, goal, how you lose, the look. A complete brief saves rounds of fixes.
- Group several small changes into one request instead of sending them one at a time.
- Use Pro for the first version of a complex game and Fast for colors, speed, text and sound tweaks.
- Every version stays in your list, so if a change goes wrong, open the previous version instead of paying to undo it.
- Check in at the gift center daily, and invite friends for extra free credits.
Free credits and the gift center
Every account created with Google gets 80 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.
Pricing questions
Do I pay to play or share a game?
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.
Is there a subscription?
No. Each pack is a single payment. Nothing renews, and there is no plan to cancel.
What does a failed build cost?
Nothing. If the model stops before the game is complete, returns broken output or takes too long, the build is marked as failed and its credits go back to your balance automatically.
Can I switch between Fast and Pro?
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.
Do you offer discounts?
Larger packs carry bonus credits (+10%, +20% and +30%). A first pack bought within 48 hours of signing up gets +30% more, and the gift center gives free credits for daily check-ins, your first game and invited friends.
Can I get a refund?
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.
