### 4/5 — where are the satoshis

*2024-05-16, version 3.8.0*

I think this game is pretty good nonetheless but i can’t find the satoshis symbol i checked the top panel of the screen and i saw nothing could you guys maybe have a video tutorial?

### 4/5 — New updates?

*2024-05-15, version 3.8.0*

Does this game update any? I’ve been playing for almost a year now and have been waiting for new levels for 2-3 months now. I play the daily challenge almost daily but would like more do to. 
Thanks!

### 5/5 — Tha aks

*2024-04-28, version 3.8.0*

Tags so

### 1/5 — No payouts anymore. AVOID

*2024-04-27, version 3.8.0*

I played this game for months and could always cash out my sats whenever I wanted to. Since the start of the year the earnings rate dropped significantly so it wasn’t even really worth playing anymore.
But it gets worse. Now you can’t even cash out anymore. I have been trying once a month for the last 3 or 4 and contacting support they say they are working on it but I feel like it’s going the way most of these games do.. ghost games.. AVOID!

### 1/5 — No sats/bitcoin withdrawal

*2024-04-05, version 3.8.0*

I saw on ZBD that this game will pay you sats to play the game but there’s no withdrawal mode SCAM

### 5/5 — Awesome

*2024-04-04, version 3.8.0*

This is a different block challenge. Nice gameplay

### 4/5 — Sats

*2024-03-29, version 3.8.0*

Se puede ganar satoshis??

### 1/5 — Sem bitcoins

*2024-03-16*

O jogo não oferece qualquer recompensa em sats.

**Developer response:** Olá!
Se Satoshi não estiver disponível em seu jogo, pedimos que você entre em contato conosco através do suporte do jogo. Verificaremos sua conta e ajudaremos você.
Estamos aguardando sua resposta. {51}

### 4/5 — No updates

*2024-02-26, version 3.8.0*

I would give it a 5 if you add more levels

### 1/5 — Can’t withdraw Sats - Support hasn’t helped

*2024-02-19, version 3.8.0*

I’ve been playing this game a long time. Recently, something is going wrong with the withdraw option. I used to be able to withdraw my sats to ZBD any time. Now it’s been weeks and I can’t withdraw my sats. I contacted support and they have no helpful solution at this time.
