Contract name (RLGL (Squid Game)) contains non-alphanumeric characters.
Not a direct threat, but may indicate unreliable intentions of developer. Non-alphanumeric chars (,.;!#*&") are extremely rare among low risk tokens.

RLGL.addLiquidity(uint256,uint256) (#745-756) ignores return value by pancakeswapV2Router.addLiquidityETH{value: ethAmount}(address(this),tokenAmount,0,0,owner(),block.timestamp) (#748-755)
Ensure that all the return values of the function calls are used.

Additional information: link

RLGL._approve(address,address,uint256).owner (#666) shadows:
- Ownable.owner() (#96-98) (function)
Rename the local variables that shadow another component.

Additional information: link

RLGL.setMaxTxPercent(uint256) (#547-551) should emit an event for:
- _maxTxAmount = _tTotal.mul(maxTxPercent).div(10 ** 2) (#548-550)
Emit an event for critical parameter changes.

RLGL._transfer(address,address,uint256) (#674-712) compares to a boolean constant:
-require(bool,string)(sell == true,@[email protected]) (#686)
Remove the equality to the boolean constant.

Additional information: link

RLGL._previousLiquidityFee (#353) is set pre-construction with a non-constant function or state variable:
- _liquidityFee
Remove any initialization of state variables via non-constant state variables or function calls. If variables must be set upon contract deployment, locate initialization in the constructor instead.

solc-0.8.7 is not recommended for deployment
Deploy with any of the following Solidity versions: 0.5.16 - 0.5.17, 0.6.11 - 0.6.12, 0.7.5 - 0.7.6 Use a simple pragma version that allows any of these versions. Consider using the latest version of Solidity for testing.

Additional information: link

Variable RLGL._maxTxAmount (#361) is not in mixedCase
Follow the Solidity naming convention.

Additional information: link

Variable RLGL._getRValues(uint256,uint256,uint256,uint256,uint256).rTransferAmount (#588) is too similar to RLGL._getTValues(uint256).tTransferAmount (#579)
Prevent variables from having similar names.

Additional information: link

RLGL.slitherConstructorVariables() (#322-811) uses literals with too many digits:
- numTokensSellToAddToLiquidity = 500000 * 10 ** 6 * 10 ** 18 (#362)
Use: Ether suffix, Time suffix, or The scientific notation

Additional information: link

RLGL.numTokensSellToAddToLiquidity (#362) should be constant
Add the constant attributes to state variables that never change.

Additional information: link

isExcludedFromFee(address) should be declared external:
- RLGL.isExcludedFromFee(address) (#661-664)
Use the external attribute for functions never called from the contract.
